On their website it says that they're experiencing DDOS attacks. Sounds like not all their servers are down however:
"Though our name server are still under DDOS attacks, your domains should be up and running fine now. If unable to reach your domain, please make sure you have all 4 name servers, ns1.dnsexit.com, ns2.dnsexit.com, ns3.dnsexit.com and ns4.dnsexit.com assigned to your domain."
I admit, I only had configured only three NS for my domain. But it doesn't make any difference, right now none of the four are available.
Good though, that they have a warning sign attached to their page now. I've been searching the web a couple of times the last two days and found _no_ news whatsover. In the event of a DDOS attack, I would appreciate a warning mail.
Of course if the attack is as bad as it seems, the downtime is not their fault and I feel with them. They are probably working around the clock on that. I wish them all the best to block that traffic out.
But anyway - I have learned that I'll need more than one DNS provider to ensure a reliable service.
