Advertisements DirecTV is much more picky on dish alignment than DISH, since it's Ka vs. Ku. Eastern Arc is higher in the sky on the east coast, so in theory it has to cut through less of the atmosphere, but that doesn't seem to overcome the technical superiority of DirecTV's Ka system. A well aligned DirecTV dish will never be out for more than a few minutes, and that won't happen very often. DirecTV's 99% claim is very conservative, in reality, they are pushing 9's. Probably not to datacenter/internet level reliability where at 99.9999% you get a few minutes per year of downtime, but certainly 99.9% or 99.99%.
