Don't panick
I have this on good authority...
Upgrade Facts. (although this may have already changed since yesterday :¬& )
Don't blame the Customer Service or Broadband tech who gives conflicting information/service, this is because they are receiving conflicting information.
Fact 1. Some areas had to be upgraded to cope; and all routers had to be upgraded to allow for new speeds, new customers automatically get the new speeds from 8th March. Existing customers should (probably) be upgraded automatiacally within a few weeks. STB customers with PACE boxes on 750 Mb who would be upgraded to 2/3 Mb need the equipment replaced to Samsung boxes or a Cable Modem installed (this is because the PACE boxes are limited to 1Mb speed)
The news of the upgrade to new customers travelled fast, NTL bosses

panicked and the conflicting information began.
Fact 3. Most customers CAN upgrade via the website speed upgrade link
http://www.ntlworld.com/data-feeds/e.../tierMigration with the exception of STB PACE Boxes that are presently on 750/1Mb (see above) and to further complicate matters any customer on XBox/PS2 and Broadband Plus will not be able to connect after the upgrade (call technical support for a fix)
Fact 4. Customers who have not registered their product correctly (mostly STB) will not be able to upgrade via the speed upgrade site because they haven't got a valid account (this is because you can get on the internet by putting in you PID/Password) but you should also have gone here
https://autoreg.autoregister.net/cgi/cablereg and registered, which creates an account/email username & password, to use for upgrade.
If you are unable to upgrade, you aint going to die are ya? Just wait a while and you'll either be upgraded or contacted with information on what to do, once the OFFICIAL upgrade for existing customers is announced by NTL.
