Monitoring
While we have not identified a root cause on our side, we have received no further reports of these `502` errors, and have not seen any additional production errors at the associated endpoint for 2 hrs, so we will move this to "monitoring."
Update
We have stopped receiving new reports of these `502` errors, and still have not identified an organic cause internally, so we are hoping that this was a temporary issue with a related service.
We will keep this open until we feel confident there are no further incidents.
If you experience any such errors, please reach out to: support@coveralls.io.

Update
We are still investigating but have not found any underlying errors in production logs for reported requests, pointing to possible latency issues with our edge service provider, Cloudflare.
No reported outages at Cloudflare, but two US centers (Salt Like City and Houston), are in maintenance mode and may be re-routing requests, adding to latency:

> Traffic might be re-routed from this location, hence there is a possibility of a slight increase in latency during this maintenance window for end-users in the affected region.
