AWS DirectConnect Access

"AWS Direct Connect makes it easy to establish a dedicated network connection from your premises to AWS.  Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections. "  From AWS Amazon

The Northern Crossroads currently has 2x10GigE links to Amazon's AWS Direct Connect in NYC.  Further details on how members can utilze these connections can be found within the Members Section.  Please use the contact page on this site if you have any questions or comments.
