Dynadot. Yesterday my website hit #1 on imgur.com. We got 15,000 sessions in 10 hours and then this DNS disruption happened. We've fallen off of imgur.com, customers all across the globe are signing into IRC and public forums to complain about how they're unable to access our services...
It's coming back online now, but Dynadot committed the unpardonable sin ... no communication. No status page, no reply in the forum, no tweets, no answer at the support number, nothing.
