Akamai have apparently stopped protecting Brian Krebs site due to an enormous DDOS, information from the site in this article: http://krebsonsecurity.com/2016/09/krebsonsecurity-hit-with-record-ddos/ can be found on Google Cache the attack was 620 Gbps in size, and using DNS amplification - and nearly double the size of the biggest previous DDOS attack against systems protected by Akamai.
One of those times when you’d really prefer getting what you paid for instead of a refund.
For what it is worth, Krebs said that they had been providing their services for free. https://twitter.com/briankrebs/status/779111614226239488
So I guess he gets both!
It wasn’t just dns amplification, which makes it even more problematic. Much harder to filter what appears (to a filter) to be valid traffic. Someone apparently has a rather large botnet capacity (hypothesis I have read range from lots of IOT devices to hacked consumer firewalls).
Also, apparently there are lots of other DDoS’s happening right now as well.
Hopefully he’s able to secure a new hosting setup and get back online. He does a lot of valuable journalism, and I would be very sad to see him offline long-term.
