Asana api is not stable, sometimes very slow

Recently(From UTC 2023-01-28 05:00:00), the api timecost is not very stable. sometimes it use only less 10s, but sometimes it costs 30s - 60s.

Before the time, we use this api over a year, and it’s very stable, so it’s a little strange. can you help check and give some insights? Thanks,,this.custom_fields,this.completed_at,this.created_at&limit=100
