UPDATE: We've been asked to remove Fast4's FULL CEO statement by EurISP as some aspects are in legal dispute, due to this the item has now been re-written. Further updates to follow.

Small UK ISP Fast4 has become embroiled in yet another dispute with one of its broadband suppliers, EurISP, after it attempted to migrate customers onto a new platform supplied by MurphX but ran into problems while doing so.

The news relates to an earlier article this week in which the ISP announced the replacement of its controversial "unlimited" broadband product (EurISP based) with a new series of capped packages (MurphX based) - here. Fast4s CEO stated that "endless months of unsatisfactory service" had contributed towards its decision to migrate.

It's understood that the ISP requested broadband migration codes (MACs) for all its customers from EurISP over 15 days ago, yet a series of alleged problems at EurISP's end has limited Fast4's access to the MACs.

Fast4s CEO, Steve Kaye, claims that they, “were given a web page to generate our own MAC codes” but that this page “was offline more times than on and kept being taken away”. Fast4 alleges to have had so many problems accessing the page that it eventually tried contacting Ofcom to get the problem resolved.

Unfortunately Ofcom appeared unable to help and later confirmed to Fast4 that EurISP had issued MACs that complied with its GC22 migration code rules. Kaye continued, “The ‘grey’ area was whether the published code actually meant that they had to give Fast4 access or actually supply the codes themselves.” Fast4 believes that the situation exposes a loophole in Ofcom's GC22 migration code rules.

EurISP was not able to comment on Fast4’s complaint but confirmed that no end users had been cut-off. We’re currently awaiting some additional information from Ofcom.
