Windows Server 123 days uptime

This was the uptime of the Windows Server that hosts our TFS and a database server, it survived several reconfigurations of sharepoint and IIS during the 123 days, but I had to restart it yesterday. I hoped that a restart would fix a problem with sharepoint I was having, but it didn't help =(, it feels like I pointlesly slaughtered it for nothing, it's not everyday that I see such a stable windows installation.
