Fiber sabotage in the Paris region

Fiber sabotage in the Paris region

On May 5th, a massive Internet outage occurred for companies and employees confined to the south of Paris following acts of sabotage on the Orange fibre network. This was a major blow at a time when more than 100,000 of the operator's customers are teleworking.


In addition to teleworkers, entire corporate networks are being badly affected. And this act of sabotage is likely to have a major impact on the services of other operators. A ZDNet reader and system and network administrator for a company operating two data centers in the Paris region, Justin reveals that the incident began yesterday at 9:30 am: "Despite the redundancy of our 10 BGP fibers, we were heavily impacted. At our level, we had 6 fibres out of 8 cut, with the operators Iliad, Zayo, Sypartech and partially Jaguar". At 10:00 am this morning, he reported that he still had "one fiber in default between his two datacenters".


10 cables were severed at the dismantling machine in the communes of Ivry-sur-Seine and Vitry-sur-Seine yesterday. Orange's internet and telephone network is therefore severely disrupted in the Val-de-Marne and part of the city of Paris.

After noting the damage, the operator dispatched technicians to the site to carry out the necessary repairs. Orange estimates that 34,000 Internet customers and 12,000 business customers are potentially affected by the outage. Orange Ile-de-France's communications department said: "The priority customers identified are being restored as a matter of priority, the technicians will be taking turns and work will continue throughout the night for a gradual recovery and an end to the recovery is planned for Thursday night for Ivry-sur-Seine and is currently being assessed for Vitry-sur-Seine".


The operator filed a complaint and the department's judicial police was seized.

According to franceinfo, a note from the territorial intelligence services mentions a clear upsurge in acts of "degradation" and "sabotage" throughout the territory. 27 incidents have been recorded since the end of March. While these facts are not claimed, the majority of territorial intelligence agents favour the ultra-left route.

At the beginning of April, two relay antennae were set fire to in a small commune in the Jura for an estimated loss of one million euros. A fibre-optic cable was cut in the Gard department, depriving more than 23,000 subscribers of telephone and Internet access for 12 hours. Damage to base stations was also reported in Italy, the Netherlands and the United Kingdom.

According to this note from territorial intelligence, the authors would seek to destabilise economic activities and teleworking through such sabotage.

Digital Transition: Developing Local DCs

on Thursday, 07 May 2020 Posted in Archives Rezopole

Digital Transition: Developing Local DCs

The Urban School of Lyon continues its conferences entitled "The Wednesdays of the Anthropocene". This week's theme: the impact of digital technology on regional planning with Cécile Diguet, urban planner, director of the Urban Planning and Territories Department of the Paris Region Institute and Jean-Vincent Bayarri, architect of Information Systems at the Metropolis of Lyon.

As a partner, Rue89Lyon publishes a podcast of these forums. Jean-Vincent Bayarri, also wrote the text below.


The intelligent city relies on important digital infrastructures, especially data centers. How are these infrastructures deployed on the territory? What issues are raised by their spatial integration? Constraints or opportunities for an ecological factory of the city? Are digital actors the new protagonists of the urban project?


Initially, containment...

Videoconferencing, streaming, telecommuting, e-commerce, online gaming are in this period of confinement even more widely consumed than usual by the French.

Many articles in the press explain how consumption induced on "networks" alone can be problematic, at the risk of "slowing down" or even "paralysing" the Internet.


"The networks"

Above all, the Internet is a set of interconnected machines, i.e. multiple routes, managed by a multitude of actors: operators, public or private structures, associations, large companies. The term "network" is actually vague since it is a multitude of interconnected networks. At the end of the chain is a server infrastructure that must meet the high demand observed in this period of containment.


While it is true that some networks can sometimes be scarce resources, particularly mobile networks, most are well sized in France to carry the traffic.

So when the website of a hypermarket brand, overwhelmed by the requests of confined consumers, displays a message asking to wait, is it the fault of the "network"? Certainly not.

The problem can often come from the last link in the chain, the "server" carrying the resource and the content consumed. How do you know when and where to align sufficient resources to meet demand?



This is the importance of data centers, since they allow multiple servers to be quickly assigned to specific tasks.

And this capability also applies to the datacenters themselves! Just as the Internet is meshed and decentralized, the strategy adopted by companies like Netflix is a very wide distribution of data centers: on several continents, in several cities, and even as close as possible to the user, partly at the ISPs themselves. It is also a common practice in most companies to distribute resources across multiple data centers for reasons of security, redundancy and high availability.


Proximity, a technical, economic and strategic asset

Some cities have a considerable asset: a GIX (Global Internet eXchange point), i.e. a local Internet exchange point. In Lyon, this is LyonIX, which is managed by Rezopole. Companies or administrations that wish to do so can connect locally to this GIX and exchange via the Internet "locally".

Thus in the Lyon metropolitan area, a very significant part of Internet traffic is consumed by Google services (Maps in particular). Since Google is present on LyonIX, access is not only instantaneous (very low latency) but also free of charge. The rest of the Internet traffic is sold through the (paying) pipes of a forwarding agent.


Beyond purely telecom costs, the logic of economic development is clear: the more Internet infrastructure is present locally, the more investors are attracted to build local datacenters. This rhymes with more jobs, more value created, and an easier digital transition.

The interest is also strategic, since putting your data in the "cloud" means putting it in someone else's datacenters. A varied and local offer of datacenters therefore makes it possible to keep company data on national soil, in better security conditions (RGPD for example), which represents a certain digital sovereignty.


Digital transition, ecological?

"To save the planet, print this message only if necessary". This maxim could almost sum up the digital transition issue by itself.

Videoconferencing, the development of mobile digital counter applications, these are just a few examples of very concrete applications - made possible by the presence of these infrastructures, these networks, these data centres in the city - which also facilitate the ecological transition.The data centres themselves are working on this with the reduction of the energy efficiency factor or the reuse of heat produced by the district heating of the surrounding area, or even a 100% operation on renewable energies.


The digital revolution has given data centers a now multiple importance (economic, social, ecological) in the city as well as other essential structures. A central link in regional planning and the digital and ecological transitions, which are far from being in opposition, are perfectly complementary.

RIPE opposes the "New IP" plan

on Thursday, 30 April 2020 Posted in Archives Rezopole

RIPE opposes the

RIPE, Europe's Internet governance body, opposes a proposal to reshape basic Internet protocols supported by the Chinese government, Chinese telecommunications companies and network equipment provider Huawei.

The proposal, called "New IP", is a reworked version of the TCP/IP standards to support new technologies. It includes a "shutdown protocol" to shut down faulty parts of the Internet and a new governance model that centralizes the Internet and puts it in the hands of a few critical node operators.


Submitted last year to the International Telecommunication Union (ITU) and published last month by the Financial Times, the new proposal immediately drew criticism. To the general public and privacy advocates, it is an obvious attempt to hide Internet censorship features behind a technical overhaul of the TCP/IP protocol stack.

In short, an attempt by the Chinese government to export and impose its autocratic views on the rest of the Internet and its infrastructure. Especially since several countries such as Iran, Russia and Saudi Arabia have given their support.


On its blog, the Regional Internet Registry for Europe, West Asia and the former USSR, RIPE NCC, has officially spoken out against China's new IP proposal.

Marco Hogewoning, acting director of public policy and Internet governance at RIPE NCC, says "Do we need New IP? I don't think we do. [...] Although there are some technical challenges with the current Internet model, I don't think we need a new architecture to solve them."

Any attempt to overhaul Internet protocols should be left to the Internet Engineering Task Force (IETF) and not the ITU, where political influence is more important than technically sound arguments, he said. RIPE is also concerned about the desire to change the decentralized nature of the Internet.


The organization expressed its concerns in a paper sent to the ITU in February this year: "RIPE NCC is deeply concerned about what has been proposed here.[...] We are particularly concerned that this proposal represents an opportunity to move away from the traditional 'bottom-up' decision-making model. We also believe that the technical justification presented is flawed and find the alternative designs suggested to be both unrealistic and unproven".


With the new proposal due to enter the test phase in 2021, Hogewoning urges national Internet governance organizations to contact local decision-makers and recommend voting against it as well as a vote at a later date.

The FFT is calling for "numerical responsibility"

on Friday, 20 March 2020 Posted in Archives Rezopole

The FFT is calling for

Due to the containment caused by the coronavirus outbreak, telecommunications operators are expecting an increase in the load on their infrastructure.

Invited by franceinfo on 17 March, the president of the French Telecommunications Federation, Arthur Dreyfuss, called for "digital responsibility" to avoid saturation. He warns that operators "may need to adapt" and "prioritize" certain uses to cope with these peaks in connections.


franceinfo: Will the infrastructure withstand the shock?

Arthur Dreyfuss: More than 15,000 technicians and engineers from all telecom operators are mobilised to ensure that the networks will hold up for the next few days, weeks, or even months. We are entering an era of social discipline and we must also enter a period of digital responsibility, both individual and collective. This is a completely new situation. The bulk of the population will be at home at the same time, all day long, for the coming weeks and months.

We are on the verge of a rise like we have never seen before. The operators are fully mobilized and we are working hard to make sure they can operate.


Does that mean rationing digital consumption?

No, but there are everyday gestures to be apprehended. At home, for example, it's better to use Wi-Fi to make calls, work, communicate and get information. This makes it possible to switch to fixed networks with greater capacity than mobile networks.


But we are going to combine telecommuting, distance learning for children, digital entertainment... Aren't the networks going to overheat?

We are used to absorbing consumption peaks, but we are going to live with a continuous increase in consumption. All individuals and companies must adapt and prioritize. It is a collective responsibility.


Could the operators come to curb the most consuming uses?

In this period, the priorities are the health of the population, working at home, the pursuit of economic life... We may indeed need to adapt to meet these priorities and we will work with all the players to adapt if necessary.

It's like the highway crossings at the end of July, beginning of August. You have to know how to adapt your consumption in the same way that you sometimes adapt your traffic.

Croissance du nombre de DataCenters à Lyon

on Wednesday, 07 August 2013 Posted in Archives Rezopole, Archives LyonIX

Croissance du nombre de DataCenters à Lyon


In 2013, many new DataCenter have been created in Lyon. The Greater Lyon experienced a shortage a few years ago but is now in a position to insure the future. Besides public DataCenters (Education, Research, or local government services) and DataCenters dedicated to a single company, hosting commercial DataCenters are booming in Lyon and its region.

It is worth mentioning that the set back was important: till 2010, there were only 5 DataCenters that may host racks. Now nearly twenty players can offer hosting servers. Rezopole has produced a map of these centers. And several projects are still under construction near the capital of saplings. Lyon city has caught, up in less than 10 years, its delay in this field. An interesting detail: all DataCenters recently created (Maxnod, DCforDATA, FMI, CFI, One-System, SynAAps) joined Lyonix from the beginning of their activities !
