Microsoft shrugs off MyDoom attack - News - ZDNet:
"Microsoft has created an alternate Web site for people whose PCs are infected with MyDoom.B and who want to get security information but cannot contact the main site because of a mechanism in the virus that blocks some 65 Web sites, including Microsoft's home page. The alternate site, which starts with 'information' rather than 'www,' lets people see the regular home page content."
