Wow, learn something new every day. I think Hughesnet is a 24 hour quota. I've only exceeded it once with help from some teenagers. Once they throttled my connection it was basically unusable. I could get a tiny web page or two, but could not do IMAP or SMTP to get or send email.
Hughesnet changed its FAP about a year ago. It had been reasonable and now is draconian. When you've been FAPped your service is a useless POS...slower than 28.8 dialup. DSL here I come!
