I purchased one of your online training courses for one of the kids but it's unusably slow. The character echo on a key hit is +/- half a second. Page refreshes take about a year. Even scrolling up and down a page is painfully slow - about the same speed as an old telex machine (if anyone remembers those).
I've tried the connection with two DSL lines, an HSPDA GSM modem, three different machines and two different OS's. Safari online, Youtube and other content comes down fine so I don't think it's a line or peering problem. Maybe your training site is overloaded or something.
I'd be happy to try and help. Is this online training course a course offered by the O'Reilly School of Technology? If so you will please want to contact them here:
