Current status: We're investigating an issue with Snowflake Data Cloud. We'll provide an update within 60 minutes.

Customer experience: Customers hosted in the specified regions may experience intermittent Snowsight login failures, elevated page load times, or session timeouts when accessing the web interface. Affected users may encounter errors such as "Failed to fetch" and "Execution failed", or HTTP 503 Service Unavailable messages. The issue is intermittent and does not affect all users or login attempts simultaneously; retrying failed requests generally results in successful connection.

ETA: An ETA is not yet available. We'll provide one as soon as possible. In the meantime, we recommend that affected customers using replication initiate their failover procedures.

Workaround: There are currently no available workarounds for this issue beyond retrying failed requests.
