Microsoft recently thwarted the biggest attack DDoS never recorded by its services in terms of speed. This attack, which occurred last August, allegedly targeted an Azure center, the name of the infrastructurecloud from the Redmond firm. For about ten minutes, the network would have suffered an assault of dizzying power with a peak recorded at 2.4 Tbps (2400Gb per second).
A figure comparable to the attacks that hit Amazon Web Services and Google in the past. Both suffered attacks with peaks of 2.3 and 2.54Tbps respectively. In terms of the raw amount of data, according to The Verge , it is would even be the “biggest DDoS attack on record”. An assertion that is difficult to verify, but which says a lot about its magnitude.
70,000 machines involved
This is particularly important in the case of an attack.as DDoS (Distributed Denial-of-Service). This maneuver consists of flooding the targeted network with unnecessary requests in order to saturate it; if the attack is of sufficient magnitude, the network is therefore catatonic, and all associated services are disrupted.
Often these attacks do not come from a single source, especially on this scale. They are led by a “botnet”, an army of zombie machines infected by upstream hackers. In this case
Better safe than sorry
Despite this massive data flow, Azure services have been able to hold their own without impacting services. Fortunately, knowing that many businesses and institutions depend on it.argement of Azure today, some of them very large.
A success that their teams cannot fail to be proud of; Admittedly, stemming an attack of this magnitude requires a very well-prepared infrastructure. And apparently Azure did it without batting an eyelid. In its press release, Microsoft explains that its architecture would be able to absorb “dozens of terabits” before succumbing to a DDos attack.

For individuals or less muscular businesses, there are services that can protect against them. The best known is certainly Cloudflare , which claims to have already stopped a 1.2 Tbps attack on behalf of a client. But the situation is different for large services, such as GiitHub which paid the price in 2018. And at a time when DDoS attacks tend to increase, it will be increasingly important to be armed to respond to them.
