INC20000294
Snowflake edited its 10-20 07:22 UTC incident update to correct “and issue” to “an issue” and adjust a truncated closing sentence. The edit was wording-only; it did not change the reported availability-zone issue, automatic workload relocation, or coordination with the third-party cloud provider on a fix.
