With apologies for not posting earlier about this, but this morning the DOS attack expanded to all of our nameservers, however we have managed to maintain DNS availability.

So far every single customer who has reported a problem with DNS availability over the course of the DOS attack has, upon inspection of their domain's nameserver delegation, only been delegated to a subset of the full nameserver cluster.

In many cases users using third-party registrars were still only delegated to 2 nameservers. This misses much of the benefit having an expanded nameserver cluster exposes your domain to elevated risk of DNS-outage during events such as this.

So please, if you're using an external registrar, check your delegation and make sure your domains are delegated to all 6 of our nameservers:

NS1.EASYDNS.COM
NS2.EASYDNS.COM
NS3.EASYDNS.ORG
NS6.EASYDNS.NET
REMOTE1.EASYDNS.COM
REMOTE2.EASYDNS.COM

Your status page says that ns6.easydns.com null routes requests. Why would I want to add this DNS server to my registrar right now?

Thanks,
Val

Right now, you wouldn't, but in general, you want to have all 6 in your delegation. After today we are going to be making changes to NS6, probably moving the cluster to a new datacenter.

Mark,

we continue to see persistent outages of

ns1.easydns.com
ns6.easydns.net

It would be very beneficial to post more frequent updates during this attack. We were guessing about issues for this morning and all but remote2.easydns.com were out of commission.

DNSreport is syaing theis morning that

A timeout occurred getting the NS records from your nameservers! None of your nameservers responded fast enough. They are probably down or unreachable. I can't continue since your nameservers aren't responding.

does this mean that all of your DNS servers are now out of action?

We added the extra 2 (NS6 and NS2) yesterday as advised in the original post.
