Who AS680 is reached through

The AS just before AS680 in the paths our looking glass collectors hold, for 60 of its prefixes. Usually a transit provider, sometimes a peer. The number is how many of those prefixes it was seen on.

Provider authorization

AS680 publishes an ASPA naming these providers. 5 ASes name it as a provider in theirs. Check a path.
