Boston’s Innovation District has become a trendy business address, and Comcast Corp. says its high-speed data network for the area is one of many reasons why.

Comcast is marking the one-year anniversary of its completion of wiring up the district with its highest level of data services for business customers. According to Comcast, Internet speeds in the neighborhood are 14 times faster than they were before the upgrade. Such services are not only ideal for high-tech start-ups, but old school businesses as well, Comcast contends.
