I liked the following quote:
"This will be the second time this year we have increased the speed of our blueyonder broadband services, doubling the original bandwidth with no increased costs and no introduction of caps," explained Eric Tveter, president and chief operating officer at Telewest Broadband.
It sounded like a dig at NTL with their
recently announced speed increases with caps!
