Hello all,

Mystified. A drupal module on our site makes a call to an OCLC server to 
get status of chat service. This has been working fine until this morning.

I can open a browser and successfully browse the URL of the status 
service. But when I use file_get_contents() or php-curl (or command-line 
curl for that matter), on the same box, I get a domain lookup error, see 
below. What the heck is going on? TIA!

www.questionpoint.org +short
132.174.11.16

yitzchas_at_ubu-dev:/www/websites/drupal/sites/all$ curl 
"http://www.questionpoint.org/crs/servlet/org.oclc.chat.QPWOnlineStatus?library=10253&rid=0" 
-m 3 -v
* name lookup timed out
* Couldn't resolve host 'www.questionpoint.org'
* Closing connection #0
curl: (6) name lookup timed out
