Overload of our API - an unusual volume of API calls coming from multi-teams tenants. As a reminder, our APIs are used for processing our workflows as Guest registrations or Administration authentications.
Thus, these API calls produced a few queries that took unexpected duration to run, hogging database resources and preventing it from processing any other queries (such as Guests registration or administration authentication).
Action 1 - Monitoring - Done
Monitoring detected an overload on the database without producing a critical alert
Change the alert thresholds to raise a critical alert
Action 2 - Patch - In progress
Optimize queries performed by our Admin API on multi-teams enabled tenants to reduce database stress
Action 3 - WAF - In progress
Activate WAF to reduce unwanted traffic ( bot, monitoring, etc.)
