Cogent Network Status/DNS Server Status Description:
Date: 10/05/2005

Level 3 has partitioned its part of the Internet from Cogent’s
part of the Internet by denying Level 3’s
customers access to Cogent’s customers and denying Cogent’s

customers access to Level 3 customers. Level 3
terminated its peering with Cogent without cause (as permitted

under its peering agreement with Cogent)
even though both Cogent and Level 3 remained in full compliance

with the previously existing interconnection
agreement.

Many Level 3 customers can still exchange traffic with Cogent

customers because the Level 3 customer is multi-
homed, i.e. it also has a connection to Cogent or to one of the

many other networks with which Cogent has a
peering relationship. As described below Cogent is offering

a solution to Level 3 customers that are not multi-homed.

Cogent will offer any Level 3 customer, who is single homed

to the Level 3 network as of October 5, 2005,
one year of full Internet transit free of charge at the same

bandwidth currently being supplied by Level 3.
Cogent will provide this connectivity in over 1,000 locations

throughout North America and Europe.

Cogent is committed to an open Internet. The existing

interconnection facilities between Level 3 and Cogent
remain intact. Cogent hopes that Level 3 will reactivate

these connections, restoring a full level of service
to their customers.

transit, please call:
