For several weeks, we encountered persistent quota limitations on Vertex AI (also in the europe-west1 region). Despite multiple attempts to request quota increases, we received no substantial response or support. Then, on October 24th 2024, our quota was abruptly set to 0 without any prior communication.

We attempted to resolve the issue today (October 25th 2024) by switching to AWS Bedrock. Unfortunately, claude-3-5-sonnet seems to be unavailable across all AWS regions as well.
