Remember the Arlington County/Earthlink wifi project I wrote about back in April?  Well, Earthlink did secure a contract with the County, but now that’s been put on hold as a result of Earthlink’s financial problems (as has Alexandria’s network, which has been partially built).   The good news is that no one’s relying on either of these networks at this point, but it does highlight the importance of building contingencies for situations like these into municipal wifi contracts.  It will be a shame if that equipment in Alexandria simply sits on the poles while Earthlink sorts itself out (Om Malik is reporting that Earthlink is considering selling its municipal network division).
