NEW THIS MONTH
Zen Internet launches two new broadband products today - Zen 8000 Active and
Zen 8000 Pro - to replace the Home 500, 1000 and 2000 services. Priced at
£24.99 and £34.99 per month respectively, the new products offer radically
faster broadband speeds (up to 8Mbps) at no extra cost. Trials have shown
that it is not commercially viable to offer completely unlimited usage with
download speeds of up to 8Mbps, of course, which does means the introduction
of some usage allowance for the first time. Following today's launch, Zen
customers currently enjoying Home 500, Home 1000 and Home 2000 will continue
to receive the same services, and needn't do anything if they don't want to
change, but they have the option of moving up to one of the new products
with no transfer fee - whenever they feel the need for more speed.
