DI and Eastern here, moving to Henderson next week and hoping this problem goes away but they're internationally throttling upload speeds in Las Vegas and I have no idea why and they're not giving any answers. Submit an FCC complaint here, they won't do anything until you submit a complaint, if you call they'll just try to get you to pay their nonsense blue glove services to send a tech out there that'll blame your equipment and not rectify the problem. here is the link to submit the complaint:
