Postmortem
Beginning at 2018-07-17 10:39:17 Pacific, our upstream provider had a partial network outage in their Chicago data center. After determining that the API and UI proxy could not talk to the backend endpoints, we started the recovery plan of moving the proxy’s IP to a hot spare proxy. However due to maintenance blocks in our upstream provider’s system, we were unable to make changes to the IP allocations. After 11 minutes, network connectivity was restored.
