Courier: Message Delays on Send Pipeline
Affected components: API
Timeline of updates
- investigating
The Courier team has identified an issue where there are significant delays of up to 10 minutes for messages. We are currently investigating and looking for a root cause to mitigate. Updates will follow.
- identified
Backed-up messages were caused by a bottleneck in our system, which has started to catch up. Messages will stabilize as the bottleneck clears.
- monitoring
Message bottleneck has cleared and the queue has stabilized. We will continue to monitor.
- monitoring
Messages have stabilized but we will continue to monitor.
- resolved
Messages have recovered and pipeline is stable again.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.
How the archive is checked, and what it cannot prove.
