On May 30th 2022, Tink experienced an outage between 12:21 and 13:05 (CET) affecting the availability of the components responsible for end-user authentication. Successively, these components continued to experience degraded performance affecting usage intermittently until 14:15 (CET)
The root cause of this outage was a change deployed by one of our engineering teams which affected several underlying services responsible for end-user authentication.
After the changes were deployed, monitoring alerts for the underlying failing services were triggered and our engineering teams started investigating the issue.
To bring the service back to an operational state, the team rolled back to a previous working version and restored the availability of our products at 13:05. At 14:15 service was fully restored after the faulty changes were identified and reverted.
As a consequence of this incident we will focus on the following actions to prevent similar scenarios from occurring again:
