I am in this DC, and we lost power to all of our racks but one. Power was restored about 2 hours later. I would assume Cloudflare had some significant failures in equipment due to the power drop. We lost a couple of servers that didn't come back up, which is not uncommon problem with hardware that has been running without a power-off for 4-5 years.
On yesterday's post someone that used to work at CF mentioned that PDX is "the brain" and if it goes down data stops propagating and starts getting stale. It's crazy to me that a company that is so critical to SO MUCH of the traffic on the internet doesn't even have a failover strategy for "the brain" of their operation.
It's amusing, I have plans on how much service degradation I can accept and what I need to keep working in the UK if the Thames Barrier is breached (which would flood most of the UK's internet connectivity in places like Telehouse, Sovereign House, etc)
To have 30% of the internet relying on a single building in a single city is hilarious.
