I already sent an email to support@peeringdb.com<mailto:support@peeringdb.com> about this, but I'm uncertain they are receiving email properly, so I'll mention it here as well. I hadn't seen mention of it already anywhere.
I'm seeing MySQL errors when attempting to query peeringdb.com this morning. I'm assuming the admins or friends of admins lurk here. 
IE:
Database error: Invalid SQL: .....<edited>
MySQL Error: 1030 (Got error 28 from storage engine)
Session halted.

The box that peeringDB is on is old and cranky. People are working on
moving it to a better box.
However, when the web interface goes down, usually you can still get
information with the whois and finger interfaces:
d82h214:~ Darius$ whois -h whois.peeringdb.com AS4436
General Network Information
And of course, this is what I meant by the finger interface:
d82h214:~ Darius$ finger as4436@peeringdb.com
Still early.
Hey,
Anybody able to access peeringdb today?
Regards,
Righa Shake
web site is down but traceroute is ok.

FWIW, server move is complete which should mean the end of outages, feel
free to email me or support@peeringdb.com with any outstanding issues.
