Fire Alarms Systems

update

: Gizmodo calls bullshit on these allegations. They probably true that this attack was not a "threat" to the Internet in general, but I think Gizmodo rejecting the resolution of potential problems open.

We have long known that there are many people out there who

Spamhaus aversion, one of the best known suppliers of a blacklist of IP addresses of spam. For what it's worth, there are times when it feels like Spamhaus can go too far in the declaration of an IP address or range of IP addresses for spammers. And, to some extent, it seems that some of those who use the Spamhaus trust him a little too hard. That said, Spamhaus does important work to help stop the internet being overrun by spam, and that's a good thing. But sometimes it bothers people are not particularly pleasant. Last week, Spamhaus added CyberBunker hosting company for spamlist. Someone did not like, and thus began a DDoS attack very helpful recursors open DNS. Spamhaus was Cloudflare, I was able to mitigate the worst of the crisis.

But ... that lead to the second round, which was behind the denial of service was much, much larger attack by a group of suppliers who offer Cloudflare with your bandwidth. Basically, it's the massive firepower directed at key points on the Internet. And it was a big deal. Since the blog Cloudflare is far from being too expressive on the whole, but just the fact that it takes account of the attack came close to "break" the Internet should allow you to wake up.

Tier 1 network bandwidth is not buying anyone, so most of the weight of the attack being carried over by them. Although there is no direct visibility of traffic loads that were, says a leading Tier 1 supplier exceeded 300Gbps traffic-related attacks this attack. This would make it the largest attack ever recorded.

challenge attacks of this magnitude is the overwhelming risk systems linking the Internet itself. Rising routers that can be purchased in most ports of 100 Gbps. It is possible to attach more than one of these ports to create a capacity greater than 100 Gbps, however, at any given time, there are limits to the amount of these routers can handle. If this limit is exceeded, the network becomes congested and slow.

These days, these attacks have increased, we have seen the congestion through several Tier 1 is important, especially in Europe, where most concentrated attacks, which affected hundreds of millions of people as they have browsed pages unrelated Spamhaus or CloudFlare. If the Internet was a little slow for you in the last days in Europe, this may be part of the reason.
