AT&T Internet Services (ATTIS) Dedicated Internet Access is based on a Cisco-Powered Network. All ATTIS POPs are designed to Carrier-Class Standards. ATTIS has completed a state-of-the-art OC-192c National IP Network, providing for diversely routed OC-192c circuits engineered to facilitate fiber and hardware redundancies and accommodate any network or hardware facility failures.

All ATTIS Central Offices (COs) and POPs are dual-redundant in power and connectivity. Supplemental power-generating facilities eliminate long-term power outages and rolling blackouts. ATTIS's recommended network design provides redundancy at all links and access points; therefore, you will not experience any single points of failure. ATTIS Dedicated Internet Access provides for redundant core switches and backbone routers, as well as maintenance spares for all critical components at all POPs.

ATTIS peers at all National Peering Points, and maintains and manages the Chicago and California NAPs. ATTIS also peers publicly and privately at multiple peering points throughout the nation. Due to non-disclosure agreements and the proprietary nature of this information, ATTIS is unable to release information concerning peering partners at these multiple public and private points.

ATTIS's network is architected to run at 200% capacity, meaning that it is engineered to be 100% bandwidth-redundant among POPs. Beyond the obvious reliability benefits, this allows for rapid growth and quality of service. ATTIS's Network Planning and Architecture division continually tracks bandwidth use and growth requirements to ensure that augments go into place prior to traffic approaching internally established thresholds.

We realize that you may not have always considered ATTIS as a Tier 1 Internet provider. But our track record speaks otherwise. We provide Internet network solutions not only to many of our millions of business and consumer customers, but to our competitors as well, the so-called Tier 1 providers.

For example, our California and Chicago Tier 1 NAPs are among the top Internet exchanges in the world, measured by both number of customers and traffic load, and have provided service to the world’s major IP carriers since 1994. The California (Pacific Bell) NAP is one of six major exchange points in the US, offering service in both the San Francisco and greater Los Angeles areas. As one of the original four NAPs in the United States, ATTIS’s Chicago NAP is the world’s largest of its kind, and yet has never seen a congestion condition resulting from switch or inter-machine trunk capacity issues. ATTIS’s NAPs have sustained only two outages in seven years and have delivered 100% uptime in the most recent years.
