CoreComm's State-of-the-Art Network

Behind the scenes, your Internet connection is routed through a world-class network of equipment designed to provide you with the fastest and most reliable service possible. This network equipment is housed in buildings called data centers.

CoreComm data centers are located in East Lansing, MI, New Berlin, WI, Kalamazoo, MI, and Dayton, OH, as well as ancillary data centers in several smaller markets.

New Berlin is the hub for CoreComm's Wisconsin and Illinois operations, including all Wisconsin points of presence. The New Berlin data center includes the main usenet news system, which features over a terabyte of storage, and a mail system. CoreComm maintains a large web-caching farm with a satellite feed from Cidera (formerly Skycache) in New Berlin and includes over 100 Linux, Sun, and FreeBSD servers onsite.

More Reliable E-Mail

Dayton is fast becoming the center of CoreComm's Ohio operations, with a centralized system for mail and authentication based on Network Appliance NetApp servers.

Kalamazoo is home to CoreComm web hosting, which is a Linux/Sun based solution with redundant servers. This means if any one machine goes down, another machine will fill its place.

Faster Web Page Loading

East Lansing is the central data center for Michigan and Indiana. This data center hosts NetApp-based email for all of CoreComm's nearly 400,000 customers. CoreComm maintains Akamai web-caching machines in East Lansing, as well as several dozen Linux, Sun, and FreeBSD servers. Akamai speeds up your web site viewing, as well as making your browsing experience more reliable.

Diesel Generator

All CoreComm data centers have generator and battery backup power and are cooled by powerful climate-control systems to eliminate heat-related system failures.

CoreComm data centers and large capacity dialup points of presence are tied together with T3 and OC3 connectivity, including a redundant ring of T3's from East Lansing to New Berlin to Chicago to Kalamazoo and back to East Lansing. Indiana and Ohio will be added to this ring in the near future.

Triple Redundancy to the NAP

CoreComm's Internet traffic primarily converges in Chicago, where we have an OC3 connection to the AADS Network Access Point. CoreComm also leases 100Mbps of bandwidth from GTE Internetworking and 45Mbps from UUnet at the Chicago NAP. In addition to the Chicago NAP, CoreComm maintains T3 connectivity with backbone providers Cable and Wireless, Sprint, Verio, Norlight and Time/Warner Telecom.

Multiple network connections increase your connection speed and deliver a consistent level of service, something a smaller ISP with a single connection can not offer.

Fore ATM Switch

CoreComm uses Cisco 7200VXR routers in the data centers and Cisco 2600 series routers in the smaller markets, which connect via T1 to one of the data centers. Voyager uses a Juniper M20 in the Chicago NAP for peering with other AADS clients. CoreComm's internal T3 and OC3 network uses Fore ATM switches, which provides greater flexibility and the ability to offer private virtual networks to business customers.
