With Rita closing in on Texas I'm sure massive amounts of the state will experience outages.

HAN is hosted on servers in Dallas, Texas. While this is further inland and may not physically be effected by the hurricane much, it could disrupt power to Dallas.

In the case that it does and you cannot access HAN, this is most likely the reason.

This all depends on how the outages effect Dallas, and I'm not sure how that will be.

Thanks
