FWIW, this is a pretty good summary of the situation.
To save anyone else a click, this is not https://nats.io/ that I was thinking of.
But nats.io has jetstream.
One thing stood out to me from skimming the report: That despite the system only handling one message (without PII) every 10 seconds the support engineers couldn’t identify which message caused the system to fail from the logs. That is wild.
The report mentions non-unique waypoint names about 4000 nm apart, but not which ones. This post on Mastodon claims that they were: DVL for Devil’s Lake, Wisconsin, US; and DVL for Deauville, Normandy, France.
