Something made many jobs's duration increase a lot since 2021-09-21

By looking at jobs duration, it seems something happened on 2021-09-21 that made many jobs duration increase quite a lot.

Examples:
gitlaborggitlabgraphqlschemadumpjobmeanduration gitlaborggitlabgraphqlverifyjobmeanduration gitlaborggitlabmemoryonbootjobmeanduration
gitlaborggitlabrspeceefrontendfixturejobmeanduration gitlaborggitlabrspecfrontendfixturejobmeanduration gitlaborggitlabrspecmigrationjobmeanduration
gitlaborggitlabstaticanalysis24jobmeanduration gitlaborggitlabrundevfixtureseejobmeanduration gitlaborggitlabreviewbuildcngjobmeanduration

Interestingly, it doesn't seem to be only gitlab-org/gitlab pipelines:

Some jobs, like setup-test-env, jest, or memory-static aren't affected:
