The incident update shows no visible wording change. Snowflake continued to report healthy service since 06:40 UTC October 20, 2026, while a third-party provider availability zone remained unavailable; new workloads were blocked from that zone and routine regional software updates remained paused.

- Wording onlyEdited by the vendor
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.
