The server where RinkAtlas is hosted experienced a pretty serious hardware problem early on Sunday, July 6, 2008. The server was restored late last night, but some additional tweaking had to be done to the LAMP stack on the restored server.
Everything seems to be running well now. If you notice any issues that you'd like to report, please email me at daiello [at] rinkatlas.com.
Sorry for any inconvenience this may have caused you.
