Trying again on SERVFAIL

[Mark Andrews]

Machines still fall over. They take the same amount of time to fix now as they did 30 years ago.

You still have to diagnose the fault. You still have to get the replacement part. You still have to potentially restore from backups. Sometimes you can switch to a standby machine which makes things faster. 

I’ve seem day long outages in the last 7 days. They still happen. Personally I was happy the emails queued.

If it comes the next day, by various people's experience, it is unacceptably too late.  If you reduce that to a few hours, the total max queue lifetime cannot remain five days.
