SC2 Community APIs - ladder endpoints return 500


Last night I noticed ladder summary and ladder endpoints in SC2 Community APIs stopped working. All regions return error 500.

As a side effect, apart from third-party projects failing, profile pages on randomly return “ERROR 404 – PAGE NOT FOUND” while trying to access any information in ‘Ladders’ tab (both the summary and specific ladders are affected, some ladders work fine, some don’t).

Is there any unannounced maintenance going on?

I can confirm. What is going on?
