While some Internet users turned off their modems to support a European Internet strike, some others enjoyed completely free surfing via BT Internet's first 'toll free' weekend.
The offer of toll free access was meant to be used only by BT Internet users that pay the full monthly fee of £11.75, but savvy members of BT and United News & Media's no subscription service, Lineone, also managed to log on - meaning they paid nothing at all for their Internet surfing.
In addition, users were supposed to be automatically disconnected after two hours but one user said he clocked up over five hours of free uninterrupted use, while another continued to use the 0800 number well after the 12am cut off time.
A spokesperson for BT was unable to comment immediately on the problems, as it was the first he had heard of them.
However, the Lineone customers that used the 0800 number are now concerned that as their contract specifies connection at local call rates and not freephone, they will be billed for their Web time or even have their accounts suspended or cancelled.
