Latest Message<\/th>\nTitle: Some users’ inbound email messages containing some URLs may be unexpectedly marked as phishing<\/p>\n

User impact: Users’ inbound email messages containing some URLs may have been unexpectedly marked as phishing.<\/p>\n

Final status: We’ve successfully released the identified affected email messages and after monitoring the service, we’ve verified the issue is now resolved. <\/p>\n

Scope of impact: Impact was specific to some users who were expecting to receive inbound email messages that contained some URLs and were served through the affected infrastructure.<\/p>\n

Start time: Tuesday, October 29, 2024, at 3:30 AM UTC<\/p>\n

End time: Saturday, November 2, 2024, at 7:00 PM UTC<\/p>\n

Root cause: A recent rule set change in our automated anti-spam procedure was incorrectly blocking email messages containing certain types of URLs. This change was causing inbound email messages to be marked as phishing and quarantined because some signatures were being flagged as malicious.<\/p>\n

Next steps:
– We’re investigating how the recent rule set change in our automated anti-spam procedure was incorrectly blocking email messages containing certain types of URLs to prevent this problem from happening again.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
