It does our geeky hearts good to see the Post paying some attention to Comcast’s unpleasant, unhelpful and generally evil behavior. To be specific, they’re covering the issue of the bandwidth caps that Comcast customers can find themselves subject to at the cable giant’s whim. Every month the network’s heaviest users receive warning letters. If they don’t curtail their net use (and sometimes even if they do), their account is terminated.

Simple enough — except the service is advertised as being unlimited, and Comcast won’t disclose what the bandwidth caps are. If you’re the type to hang around BroadbandReports.com, where nerds discuss download speeds and packet loss with the meticulous dedication of performance car tuners, you may have some idea why this is. The site is rife with speculation (including some from Comcast employees) that hard limits don’t actually exist, and that Comcast actually just prunes the top users from the network every month to improve their bottom line and forestall network upgrades. If your neighbors are heavy downloaders your monthly bandwidth limit may be much lower than if they weren’t — but there’s no way to know.

That seems like dirty pool. And combined with Comcast’s recent steps to cripple P2P use (whether illicit or not), users are increasingly getting less than they paid for.

Comcast says that affected users can upgrade to business cable service, but that option is priced to reflect uptime and service guarantees that most home users can’t afford. There’s always DSL, but in most cases it’s much slower. Some lucky area residents can get FiOS service, but that may have downsides of its own.

What about you? Has anyone received one of these warning letters? If so, what’d you do?
