Two of this month’s gainers are demonstrating that bankruptcy need not be a barrier to growth – provided you can successfully jettison a damaged brand. Scandals don’t get much larger than the collapse of WorldCom, but the renamed MCI is showing strength, gaining 55K in March after adding 14K in February. Also making our leaderboard is the former Metropolitan Fiber Network, which rebranded as AboveNet when it emerged from bankruptcy last September.

1&1 Internet AG continued to gain momentum with paid accounts in its U.S. unit, gaining 21,705 hostnames in March. Almost none of that gain came from other American hosting companies, however, as 19k were new registrations and another 650 were transfers from Go Daddy, Register.com and Network Solutions.
