EarthLink asked for more time to review changes proposed to its San Francisco contract by a city supervisor: The board of supervisors might vote for a revised contract, but EarthLink wants more time to consider changes. As noted last week, EarthLink is re-evaluating its entire muni business. I said some weeks ago that it was likely EarthLink will drop its San Francisco bid because the city is 97 percent unlikely to agree to be an anchor tenant. The original contract has explicit language that forestalls the possibility, and this Chronicle article indicates that's just not on the table for a proposal the board would approve.
