[Resolved] Slow reponses times and 504s on Open API endpoints

We are currently investigating slow response times and 504s on Open API Endpoints (catalog).

Update: About 10% of traffic to catalog endpoints result in 504's. Rest of traffic is slow (up to 4 seconds response time). This is being investigated with high priority

Update 2: Around 13:15 CET, the problem has been fixed and behavior is back to normal.

Apologies for the inconvenience.
