Thanks for the info. I tried to access Labs info on icinga to see what

that might show about Labs reliability information. I'm pretty sure that I

was able to access icinga in the past. When I go to icinga.wikimedia.org I

am prompted for a username and password, and mine don't work. I can log

into wikitech.wikimedia.org. Any suggestions?


Also, is there any place besides icinga that shows reliability data? Perhaps

I am thinking of a different tool.
