Re: Some sympathy -but not a lot
Sounds like the person paying £30k/annum has a big internet pipe or is based somewhere remote and expensive. Do you host servers at the site or just need it for internet and possibly voice comms?
Have you considered a mobile (4G if available) or bonded multiple DSL service as a backup? These don't have to go via BT's core even if delivered locally by BT copper lines for the DSL.
