Payload processing stall
Incident Report for Server Density

On June 11 between 15:21 and 16:29 UTC we were unable to process incoming device payloads or web check results. This was a result of a global persistence storage failure at our provider that impacted both our payload processing clusters, designed to be redundant of each other.

Our provider has released the following statement about this outage: "The issue arose from a dependency conflict expressed in our current persistent disk implementation. This same conflict is soon to be fixed in the next iteration, the timeline of that we cannot release. The next implementation is more fault tolerant and reliable to prevent issues like this in the future, as well we have monitoring in place to reduce the risk of this affecting customers whilst we provide a permanent fix."
