Official incident from Notion
Unexpected workspace verification banner displayed to some users
-
Official
Identified
We're investigating an issue where some users may see an unexpected banner asking them to confirm whether they recognize their workspace. This does not indicate that the workspace has been compromised. Please do not select "No, leave workspace", as this will remove you from the workspace. You can continue using Notion while we work to resolve the issue.

Monitoring
The issue has been mitigated, and the unexpected workspace verification banner is no longer being displayed. This issue did not indicate that any workspaces were compromised. If the banner is still visible, please reload the page or restart the Notion app to make it disappear. We apologize for the confusion and concern this may have caused. We will continue monitoring the situation.

What our checkpoints saw
HostTracker's checkpoints, which test www.notion.so from several locations, recorded no outage of 5 minutes or longer during this incident. A provider can report a problem that affects only some features, regions or accounts, which a check of the main address does not see. The live Notion status shows what our checks see right now.
Does your product depend on Notion?
An outage like this one reaches your users through your product, and most teams hear about it from a customer rather than from a dashboard. HostTracker watches any endpoint you name - your own site, an API you call, a vendor you resell - from 300+ locations, confirms a failure from several of them before it says anything, and then tells you by email, SMS, voice call or your chat tool.
You get the same record you are reading here for your own services: every outage timestamped, with the checks that observed it.
