Another Neustar UltraDNS Outage – UltraDNS Goes Down (blog.dotcom-monitor.com)

I didn't see a better source to link to, but this seems to be impacting a lot of websites and I thought others would like to know what is going on.

Yeah -- it's annoying how many layers there are, sometimes. At first we obviously were worried a couple sites which are CloudFlare customers were having problems due to our service. Wasn't that, moved upstream to AWS; wasn't that. Identified UltraDNS later, and confirmed externally.

A sales weasel from dyn is trying to capitalise on the outage.

Here he is being trolled for it though: https://twitter.com/DynShane/status/654775378976768000
