[AT RISK 2008/004] March 8th 2008 - Electrical works planned between 0001-0200hrs

Maintenance log for March 8th 2008
Attending: dwm
Status: Completed at 10:00hrs, March 8th 2008.
Summary:

  • The rack containing the Tastycake.net server kalimdor.tastycake.net will be briefly powered down so that the rack can be connected to a newly-installed power-distribution board.
  • As a result, no services will be accessible whilst the switchover is in progress. The at-risk period will last until 0200hrs, though the colo engineers hope to have normal services resumed by 0030hrs.
  • Works to be carried out:
    • Shut down kalimdor.tastycake.net. (Completed)
    • Wait whilst the co-location engineers switch the rack over to the new power-distribution feed. (Completed)
    • Boot kalimdor.tastycake.net. (Completed)
    • Verify services are running normally. (Completed)

  • [0915] Services verified as functioning correctly. (There was a minor issue with the current experimental DNS service for the dwm.me.uk domain as a result of invalid zone configuration data, corrected. It turns out that you're not allowed a CNAME as well as an SOA for the root of a zone, but A and AAAA records are fine..)
  • [0015] Power restored, automated reboot in progress. All services runningas normal.
