When a power failure at the Hurricane Electric data center took this website down for five hours earlier this year, I looked up the Linode service level agreement (SLA) I accepted, and found that I probably made a good cost/benefit choice, but even so it’s worth revisiting at some point.

Instead, it was an easily foreseeable malfunction that should have been taken into account when the center was designed. According to a postmortem report posted by Linode – the company primarily affected by the outage – when PG&E’s line went out at the facility, a bad battery kept backup power from kicking in…
