v2 apps/console unstable w/ intermittent outages
Incident Report for Meya CX Automation Platform

What happened?

At approximately 1:00pm ET on Sept. 8th, 2021 our shared long term storage ledger (tldr; logs) entry database was experiencing greater than capacity load due to aggregate system load. We identified the bottleneck and then initiated a DB scale up operation that necessitated a short downtime at 1:24pm ET. The DB is required for bots to be online, and thus all bots when down until approximately 1:26pm ET.

How did we fix it?

  • Scaled up shared logs DB by doubling capacity

What was affected?

  • All v2 apps went offline for 2-4 minutes

  • Some apps took longer (up to 20 minutes) to stabilize

What will change moving forward?

  • We are investigating removing the dependency of live bots on the shared logs DB
  • We will add alerting for this specific load scenario on our logs DB
  • We will further increase our communication with larger customers to provide early insight into load planning

Only a small number of apps are experiencing downtime while they catch up to processing deep ledger queues.

We require an emergency scaling of one of our databases. We've initiated this process, but will incur some downtime as a restart is required.
