Gatsby Engineering was made aware of an increasing number of 503 errors that were manifesting in different forms. When Engineering saw that multiple sites had the issue, they were able to discern there was a Gateway issue. They restarted the Gateway to temporarily fix the issue. Since then, they’ve increased the number of instances of the Gateway service.
The root cause of the incident was a Gateway issue, this has been fully resolved by increasing the number of Gateway instances.
Gatsby’s Engineering Team increased the number of Gateway instances and will configure automatic scaling to make sure this doesn’t happen again.
Gatsby Engineering identified several ways to prevent this issue from occurring again by addressing how the Gateway is currently implemented and how to respond to a sudden increase in traffic.
