web sites down last night

[Jonathan Post]

 From 2:30-3:10 a.m. this morning (8 Feb 2007) the following was the
only reply I could elicit:

===============
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /~njas/sequences/.

Reason: DNS lookup failure for: exspider.research.att.com

Apache/2.0.46 (Red Hat) Server at www.research.att.com Port 80
===============

I'll go back to sleep now, hoping that everything is okay with OEIS
and its supporting architecture.
