Main server down

Post by choralia »

At the present time the main CPDL server (www.cpdl.org) and its co-located read-only mirror (www2.cpdl.org) are down. The hosting provider is having problems with a block of servers, and they think that a few hours will be needed to fix the issue.

All other read-only mirrors:

http://www0.cpdl.org

http://www1.cpdl.org

http://www3.cpdl.org

are up and running, so they can be used to search and download scores until full operations of the main server are restored.

The server is up and running again, much earlier than expected, however it is still set in a specific mode used by the hosting provider for troubleshooting. I guess that temporary outages may still occur.

My fault. I made a mistake when activating the registration process assisted by wiki admins to stop the vandals, however the mistake was hidden for a while by the caching mechanism. Fixed at 14:53 UTC.

Nobody made changes for a while, apparently. I've just slightly improved the text of the announcement, and my modification is shown regularly.

Since about one day, all pages are showing very slowly, with a light-grey empty page step before text showing.

Yes, I also noticed something strange yesterday, and the logs show quite large variations of the response time.

I rebooted the server about one hour ago, and response time seems normal and stable now.

I've been struggling with the server for several hours. I think it was a network problem at the hosting provider's infrastructure, not a server problem, as it was even difficult to reach the server and reboot it, and I also had problems with another server at the same hosting provider. Now the situation seems more stable, and I've rebooted the server to stay on the safe side.

It seems I found the culprit: a modification I introduced to prepare a SW upgrading was causing a rather large server load. After reverting the modification, the server load seems low and stable, and response time seems back to normal values.
