EveryDns.net denial of service (DoS) attacks
From the EveryDns.net site:
EveryDNS suffered a large Denial of Service attack starting on Friday, December 1st. We have taken steps to mitigate the attack and service was restored within a few hours. There will be a more complete writeup posted on Monday, December 4th, 2006. This was our first major outage due to a DoS attack in quite some time. We are currently forming a plan to enhance our architecture to better deal with such a situation should it occur again. We take actions like this seriously and are working to find those responsible.
EveryDNS is a provider of DNS services that are free to use for anyone. EveryDNS has four DNS servers worldwide that you can use. They also offer dynamic dns services for free. They are great and if you haven’t done so, I would really suggest you to try them.
Unfortunately, EveryDNS has a downside that I would like to emphasize for professional/commercial users. They have been attacked by a large botnet two times now. First time I remember was in 2003 and more recently on december 1st, 2006. In this article the owner also talks about an attack in 2001. So that would be 3 attacks. EveryDNS promised improvements and I’m sure that they will make these improvements. But if you are a professional and don’t want to take unnessecary risks I want to warn you not to use EveryDNS.
EveryDNS is a fighter against botnets. They regularly shut down botnets by removing DNS entries used by these botnets. Obviously the criminals running these botnets are not happy and therefore attack EveryDNS. EveryDNS says: “This was our first major outage due to a DoS attack in quite some time” while the last time was in 2003. That is quite recent if you ask me. The latest attack was dealt with quite fast. However the downtime of approximately 6 hours is still a lot. The previous downtime was longer if I remember correctly. Take this into consideration when deciding to use their service. They will continue fighting botnets and such, so the risk of attacks stays. You might want to consider paid services like those from Akamai instead.
I will update this article when more info is available, so check back later!
