FullHost - Toronto Data Center – Incident details

We experienced a temporary network reachability issue affecting the IP range 162.223.224.0/21. A configuration update caused some external networks to temporarily lose access to this range.

What Happened

At 3:32 PM ET, we enabled an RPKI security setting intended to improve routing security. The change contained an error that caused some networks around the world to reject traffic to our IP range.

We identified the issue quickly and rolled back the change at 3:43 PM ET. However, some providers had already cached the incorrect routing information, which delayed full recovery.

Resolution

Recovery began immediately after the rollback. Most networks had restored connectivity by 4:10 PM ET, with full global recovery shortly after.

What We’re Doing to Prevent This

We are reviewing our deployment and validation processes to ensure similar issues do not occur again. Additional safeguards will be implemented before making future routing-related changes.

We sincerely apologize for the disruption and appreciate your patience while we resolved this issue.

This incident has been resolved.

Network connectivity is begin to recover across most networks now, and a full recovery should be expected soon.
