[outages] IPv6 access to www.facebook.com currently down for me via Cogent

[Frank Bulk]

Sorry for the noise, it was confirmed to be a not-yet-fully understood issue
between our upstream provider and one of their providers.  Traceroutes now
show it flowing over Sprint.

Down for me via Cogent since 8:40 am Central.  IPv4 access is just fine.
IPv6 access from another host via NTT is fine, too, so I suspect a Cogent
issue.
