On Tuesday night many Hulu users were unable to stream video or live TV because they couldn't log in, which was bad enough. Unfortunately, Hulu suffered another outage tonight, going down again for a few hours during prime time ET viewing. Within the last hour, its support Twitter account reported that a "fix is in place" to address the login problem, but it may come a little late for users heading to bed. We've contacted the service to find out what's happening and will update this post if there's more information.
