Summary: Cooling related failure in one of our buildings that hosts zone europe-west2-a for region europe-west2. The other zones are not impacted

I guess it's worth pointing out that europe-west2 is in London, which is currently at +35°C and was as high as +40°C at one point earlier today.

Equinix LD4/5/6 (Slough, Greater London) is the datacentre affected

So N+1 is not enough? https://www.equinix.com/data-centers/europe-colocation/unite...

Valid point, but I'm assuming that they never imagined 40-degree (outside) temperatures lasting multiple hours as a threat. Slough just got hit around 40.2 degrees, first time since records began.

It's a bit of a stretch to call europe-west2 "London" when it's Slough

It's also a bit of a stretch to call it "Google" when it's an Equinix datacenter. I know this is standard across all major cloud providers, and call me old-fashioned, but personally I'd prefer a bit more accuracy in naming of each region. Instead there is obfuscation. It's weirdly difficult to find a list of which datacenters correspond to which cloud region.

how about Slough-on-Thames?

Probably better to point out to move to Finland (europe-north1) as it's only 18 degrees.

If everyone here in the south follows this advice., Finland will sink

Belgium and Finland have better capacity than London/Zurich.

If it’s a single availability zone (which I presume west2-a is), then why are so many services down and recommending moving to other regions?

I hope there is a public postmortem that explains this. I have Cloud SQL instances with high availability enabled that have been down for over 5 hours with no workaround, when (according to docs) they should have failed over to the unaffected zones within minutes.

GKE user in that region, we are down.

I think it's deceptive to say it's a single zone. We have VMs across three zones, but anything stateful on zone a is stranded, we can't get the volumes back. It's not just that the zone is down, it's that services are not easy to fail out of the impacted zone or move that's the problem.

Kind on implies regional isn't good enough to secure high availability. You need multi regional deployments. Good luck with that when the bill comes due.

No you just need regional PD
