504/503/404 errors for EU requests to SC2 API

Since yesterday 08.05.2023 arround 19:00 CET some requests to SC2 API in eu region result in 504 Gateway Timeout errors.

This includes the following:
Ladder Summary - https://eu.api.blizzard.com/sc2/profile/:regionId/:realmId/:profileId/ladder/summary..
Grandmaster Leaderboard - https://eu.api.blizzard.com/sc2/ladder/grandmaster/2...
Profile - https://eu.api.blizzard.com/sc2/profile/:regionId/:realmId/:profileId...

In addition the StarCraft II League API returns 404 for EU and season 56

Please fix these issues for the sake of SC2 community.

Edit (14 August 2023):
While the 504 errors are now gone, League data api (/data/sc2/league/{seasonId}/{queueId}/{teamType}/{leagueId}) for region eu still returns 404. Others like Ladder Summary (/sc2/profile/:regionId/:realmId/:profileId/ladder/summary) and Ladder (/sc2/profile/:regionId/:realmId/:profileId/ladder/:ladderId) result in error 503 for eu region very often (30% of the time)

As of 6th of September all requests to Ladder Summary, Match History, Profile and others apis form SC2 Community APIs result in 503 status code errors (Service Unavailable) for EU region.
