I've just sent this update over the Outages ML:
Dear Customer,
We regret to inform you that your services were affected by an incident occurred at 16:00 UTC during a routine update of a routing policy for aggregated prefixes in Telia Carrier IP Core network. This caused traffic to prefixes contained within the aggregates >to be blackholed, resulting in a impact on some parts of the network.
When the underlying problem source was traced, the configuration was rolled back to the earlier working version of the routing policy (17:05 UTC). Affected services started to recover gradually after this operation was applied. No further disturbances >related to this incident are expected.
Due to the wide impact on several customer services, a number of complaints was received by our Customer Support Centre, resulting in delays in the communication with customers via email and/or phone. We apologize for any inconvenience this incident >has caused to your services.

Really it depends on the problem source. BGP do not know either route really reachable or not. This time we was just lucky.

We have 2 ports from Telia, one in Kiev (Ukraine) and one in New York (USA). I have seen both ports simultaneously dropped traffic volume for about one hour today.
It was not critical (for us), as traffic was shifted to another links, and there was no unreachable destinations like BGP announces with traffic blackholed. But looks strange.
Thats why it is called the bridging gap protocol
While Telia barfed, it bridged the gap.
See, bgp is not all bad. There are no bad routes, only bad days
