Military computers are reportedly blocking a number of LGBT blogs and websites, including those of AMERICAblog Gay and the Gay and Lesbian Alliance Against Defamation (GLAAD), according to GLAAD.

GLAAD discovered that the Department of Defense uses a web-filtering product made by Blue Coat Services, a company based in Sunnyvale, Calif. Blue Coat responded to a GLAAD inquiry with a statement that it categorizes websites into 90 categories that range from type of content to audience to topic.

The Department of Defense told AMERICAblog Gay, “No filter is perfect and some sites may have unnecessarily been blocked. The Department Chief Information Officer will work with relevant components to address these situations.”
