OpenSRS outage


I apologize if this isn't the best forum for the question, but does
anyone know what is going on with OpenSRS?

I have multiple customers on their spam-filtering service (quite handy
until about 8 hours ago) whose MX records have been dropped. Then I
noticed two of the their three DNS servers are not responding. The
third seems to have developed amnesia.

Their website appears to be affected as well.
