We’re sorry for the downtime

Tuesday, July 8th, 2008

Last night, from July 7, 9:00 pm CEST until July 8, 0:30 am CEST our servers were not reachable, due to maintenance work on the infrastructure of the Wissenschaftspark Golm which connects our servers to the internet.

Server Load

Sunday, June 15th, 2008

Having just compiled some numbers about server load on the main Living Reviews web server, I might as well share them.

Taken together all services currently served, we’re up to 200,000 requests on an average day; that’s about 2.3 requests per second.

The majority of traffic (almost 75%) still goes to Living Reviews in Relativity. But the recently published World Atlas of Language Structures already accounts for almost 10% of all hits, which is about the traffic Living Reviews in Solar Physics sees. The remaining traffic is shared by Living Reviews in European Governance and Living Reviews in Landscape Research equally.

These numbers are basically derived from our web statistics data.

Infrastructure Monitor

Sunday, April 6th, 2008

Due to the fact that more and more services are provided on the Living Reviews Infrastructure, we had to come up with some sort of automated monitoring. Today I put a web interface on top of the monitoring database, to make the health of our services visible on the web.
