Uptime shows what the current server uptime is, events shows when the server has ever been down on the internet. It being down on the internet doesn't necessarily mean that the server crashed (although in some of the cases it did) but most likely that the internet connection for the server went down. The events will be updated if the server is ever down, within a 2 days of it being down. Events is monitored by uptime.openacs.org, and our server is checked approximately every 20 minutes (so 20 minute downtimes may really only be a few minutes).
