The Recording Industry Association of America (RIAA) web site is once again experiencing significant downtime. The timing of outages yesterday and today begs the question of whether the site continues to suffer the effects of the MyDoom.F virus, which programs machines to launch distributed denial of service attacks on www.riaa.com between the 17th and 22nd of each month.

The RIAA site was offline from March 17-24 due to the effects of MyDoom.F, which at its height was estimated to have infected as many as 45,000 machines, according to antivirus vendors.

A dynamically updating graph of the sites targeted for DDoS by various MyDoom variants is available here.
