Message 20437 - Posted: 20 Sep 2008, 10:43:26 UTC

I\'m curious, was LHC@home having network or server problems Friday morning (19 Sep 2008, between 02:15 and 05:15 US Central Time, GMT-06:00)? Was I the only one having connection problems? BOINC got the following message-set, or something very like it, more than three dozen times while trying to fetch WUs this morning. (The WU name below was changed to protect the guilty. <GRIN>)

(All times given are US/Canada Central Time, GMT-6:00)

9/19/2008 5:06:04 AM Internet access OK - project servers may be temporarily down.

Note that BOINC could reach the reference site, so I don\'t think it was a problem with my computer or my local connection. I was having problems with both downloads and uploads. Because of the connection problems, I only managed to process six very short WUs. I didn\'t get close to the 20 WUs per day limit (which is another issue...). During that time, I was also experiencing a lag of around 45 to 60 seconds on another connection to a German site, then that connection dropped completely and I\\\'m using an \"emergency\" front end to access it, now. US sites did not seem to be affected.

Cheers,

Stephen
