One of our carriers is undertaking maintenance, which will result in a BGP feed being taken offline. Routes should gracefully failover to an alternate carrier during their maintenance window.
Update (23:49): We don’t normally provide notice of maintenance to our carrier networks as it isn’t usually a necessity to do so. Services typically discretely failover without any adverse affects. However, in this instance, it has been brought to our attention that that failover was not instantaneous.Our internal measured downtime was less than 3s during BGP changes, however, some customers have reported longer outages. However, we unfortunately cannot control external ISPs or the rate at which their routing tables update - any outages seen were merely the result of out of date routing entries on external networks that had not yet been updated.
