Someone on other forum claimed the Virgin FAQ's page will be updated tomorrow (meaning 2nd May but here it is still:
http://www.virginmedia.com/help/faq/#downloadscapped
Q: Is it true that downloads will be capped?
A: Our cable services are not capped and there are no intentions to introduce any usage limits - these are unlimited.
Still the same so not updated as of yet unless you want to look at caps as not same as throttling, either way its still a limiter in either speed or amount so its a bandwidth saver, and its lies about only some areas have the throttling as UBR10 Uddingston is not offically on it but I notice its slow between mid afternoon till midnight every day for the past 6 months without downloading anything so not going over any limit, again thats down to my oversubscribed UBR.
