Latest update from Front

On Friday, Dec 19, at 14:50 UTC \(6:50am PST\), customers backed in our US-West-2 data center experienced dramatically increased API latency, resulting in the website failing to load and messages being queued in the backend. This continued until 18:10 UTC \(10:10am PST\). During this time no messages were lost, though there may have been a significant delay for messages to appear in customer inboxes. All queued messages were delivered by 21:00 \(1:00pm PST\). ‌ Customers based in Front’s EU-West-1 and US-West-1 datacenters may have experienced some delays during this time, as some systems are interdependent, but this impact was intermittent and uncommon. ‌ The root cause of this issue was the failure of a caching system. There are several database systems that support the Front application, which are supported by caching to improve performance. A recent change increased the size of some objects in the cache layer. This is not inherently wrong, and did not have any immediate impact.
