Mine has to be Contabo. 12 hours down, and their status page eventually updated to "rodent-related infrastructure damage." I assumed it was a joke. Nope. They claimed a squirrel chewed through power lines at their Hetzner PoP. No ETA, no compensation, just a stock photo of a squirrel and "we're monitoring the situation."
YMMV, but IMO if your redundancy plan can't survive one ambitious squirrel, your redundancy plan isn't one. Take it with a grain of salt though — maybe I'm just bitter from refreshing that page 400 times.
