March 16: Tight capacity in ORD and SIN (09:12UTC)

Demand in many of our regions is growing *a lot* this year. So much so that our ORD and SIN regions hit capacity faster than we could bring new hardware online. The main impact from a constrained region is that existing machines may fail to start if the physical host they’re on is above our safety margin for resource usage. Deploys also see some effect, when a valid host to place a new machine can’t be found. In this case, the incident was largely resolved by provisioning new ORD hardware and rebalancing some workloads across the region.
