We are in the process of mitigating a large scale DDoS attack against our global DNS platform. We expect service to return to normal very shortly. Stay tuned and let me know if you have any questions. [email protected]

Just for future reference, it's usually considered a good idea to put your status page on completely independent infrastructure so that it stays up even when the rest of your stuff goes down. A status page that doesn't work during an outage isn't particularly useful.

Most DDOS attacks against a company like yours are actually attacks against a specific customer. If:

a) you had a pool of DNS server names, say 20, all with unrelated hostnames

b) you assigned 2 to each customer, randomly, when they configured a domain to use your servers.

Then, a DDOS attack would impact 10% of your customers instead of 100%. (Assuming other practices, like null routing the target until resolved)

Yes please, thank you :) All my domains are down now but I understand how shitty (the panic!) it feels to have things going down. I'll be checking this.

Was going to switch to route 53 while you guys were down and switch back, but the page says it'll take a day...Might as well just wait at that point. I know it's panic mode over there, but some kind of failover record would be awesome for when this happens in the future(or an option for one).

You guys should really put a notice on your homepage or something.

Good luck.

I took your advice and transferred a domain to DNSv1. That domain is still not back online, but all the domains I left as DNSv2 have come back!
[+] ilikesnowflakes|12 years ago|reply
You guys should add an option for us to put in an optional backup DNS record in the settings.
[+] dywtk|12 years ago|reply
The quick tut on switching to DNSv1 is nice however the option doesnt exist in my account

Thanks for posting here!

Kudos for using a HN page to stay in touch

Ho quickly will the switch to v1 execute?
[+] kitnos|12 years ago|reply
hi already have OK's, but the DNS are all using the same IP :( bad sign?
[+] mindo3|12 years ago|reply
When did this attack start ?
[+] megakf|12 years ago|reply
Down again My domain down again
[+] kitnos|12 years ago|reply
do you have ETA?
[+] MuratC|12 years ago|reply
You need to provide some gift to your customers for this downtime. I am using NC for 10 years, every time on bad issues I continue to use. But this outage very bad, I lost money...

Weird, I haven't researched DNS as well as I should have. I always lived under the impression that there was this extensive DNS cache network where intermediaries responded to queries with cached results from root DNS servers.

Instead, the second that this DDos hits is the second we have websites stopping working.

How is it that in this day and age we can't have distributed caches of DNS entries at our providers of full dns databases. I mean there can't be more than like a few billion dns entries in the world total, which fits easily in a modern desktop computers RAM.

If that is an underestimate, I can't believe a single modern server wouldn't be able to mirror the world's DNS queries for at least a providers worth of users.

[+] jschuur|12 years ago|reply
Depends on the TTL (time to live) settings for the DNS entries, doesn't it?

How would one add (say) AWS Route53 as a secondary DNS?

I assume you'd make sure the DNS records are the same in both DNS portals; and then add Route53 as 3rd & 4th nameservers with the first and second still being Namecheap?

[+] wes-exp|12 years ago|reply
It seems like secondary DNS is not supported, but you can change your primary DNS with the "Transfer DNS to Webhost" option.
[+] IgorPartola|12 years ago|reply
Yes, or just switch completely to Route53.
[+] motoford|12 years ago|reply
If your site is down and you are on v2, Switch to v1. It only takes a minute and it works.
[+] jsm386|12 years ago|reply
Yeah - at least right now this worked for me. Thank you for the tip!
[+] julianc|12 years ago|reply
I switched and it's the same, still down.
[+] blissofbeing|12 years ago|reply
I recently switched most of my domains to DNSMadeEasy because they are constantly in the top for speed[1], provide a top tier anycast network and for what you get are a great value.

If you want speed and readability I suggest switching to a paid DNS provider.

BTW I'm not in any way affiliated, just like the service.

Best of luck to their support team. Outages can make tech support's life miserable. If you call in, just remember the person on the other side of the phone has likely been yelled at all morning for something that wasn't their fault. Totally reasonable to be upset at the situation, just don't take it out on the tech you're talking to!

Job security ;).. j/k! I imagine it must not be fun
[+] kennhardy|12 years ago|reply
May this have been a problem lasting for a week?

I am monitoring a few servers with DNS records. And the last week I have found all the servers unresponsive (by DNS, not tried directly) from time to time. And after an extensive amount of troubleshooting I am unable to find a problem.

[+] User7|12 years ago|reply
I don't know how this website works, but I can't see the latest posts at the top of the page! I'm looking for the latest info on the issue. Are you up and running? Should I move back to v2? Thanks
[+] derwiki|12 years ago|reply
Is there any point in freaking out or do we just have to wait this one out?
[+] tinco|12 years ago|reply
If it's absolutely critical that your users get service right now, it might be a good idea to at least prepare a migration to other DNS servers, like perhaps those of Linode. If the situation doesn't improve within an hour or so, it might be that they don't have a good way to deal with it, and the outtage might take long, depending on the depth of the DDoSers pockets.
[+] avb|12 years ago|reply
Any good suggestions for alternative DNS providers?
[+] srik|12 years ago|reply
This is so embarrassing for me. We just put out our school computer group's website up and boom - murphys law.
[+] MichaelTieso|12 years ago|reply
That would explain why I'm getting a massive amount of tickets from my clients why their site is down.
[+] kennhardy|12 years ago|reply
Down for me as well. Lost access to absolutely all of my company's services. TTL 60...
[+] micah63|12 years ago|reply
yup, our app is down : (
