I don't know the specifics of what you reference, but in a large
geographically dispersed network like NTT's backbone, I can assure you
there will always be something down somewhere. Issues can take on many
forms: sometimes it is a customer specific issue related to a single
interface, sometimes something larger is going on.

It is quite rare that the whole network is on fire, so in the general
case is good to investigate and consider each and every report about
potential issues separately.

The excellent people at the NTT NOC are always available at noc at
or the phone numbers listed in PeeringDB.

Kind regards,
