After I arrived at home after work today I noticed that the machines at my parents home network were all down and just recovering from the outage. Two of my m68k autobuilders are located there. Nothing serious, I thought, because the machines are located behind DSL and maybe there was a short DSL outage.
Some minutes later I received two mails from my UPS that there was a power outage. Well, this explains the DSL outage as well, because the DSL is not attached to the USV (located in a different room).

Thu Jul 03 17:46:43 CEST 2008 Power failure.
Ten minutes of power outage without machines being shutdown. It’s a APC UPS BR800I with 3 machines (2x m68ks, 1x PIII@550), a SCSI hardware RAID with 7 disks and a 8 port switch hooked up to it. I’m really glad that I bought the UPS earlier this year – exactly for this purpose and to prevent filesystem errors on the buildds when there is a power outage. 🙂
