Infrastructure:Incident 2015-04-23
Revision as of 03:04, 24 April 2015 by imported>Mutantmonkey
In the early morning of April 23, 2015, Whittemore Hall lost power and brought down VTLUUG infrastructure. Issues bringing hardware back up were compounded by:
- Maintenance deferred for far too long, which prevented some machines from booting on their own.
- Failure to notice the clocks on VMs were wrong due to a dead CMOS battery on wood, which prevented Kerberos from working properly.
- Lack of a dedicated sysadmin with the time and experience necessary to correct these problems.
- Lack of a disaster recovery plan.
Some steps that should be taken to reduce the length and impact of future outages include:
- Rebuild VMs like milton, which have had too much maintenance deferred, and move them to cyberdelia.
- Install NTP on all servers.
- Find a dedicated sysadmin.
- Create a disaster recovery plan.
