It appears that the recovery from the recent network/power problems in SFO2 had a hiccup.
I fully expect my droplets to go down due to hardware problems from time to time. However it would be really, really, really...
DO just posted a report (https://www.digitalocean.com/company/blog/update-on-the-april-11th-sfo2-power-outage/) detailing this incident.
In it they state:
20:15 UTC - All Droplets and services fully restored.
