I have been a XILO customer for a number of years, and whilst I've sometimes struggled to talk to their technical teams (the online ticket system is quite frustrating) - I have never had any problems with the service they provide.
I've been contacted by their team in relation to the closure of O2's wholesale LLU (LLU - O2W) offering, and offered the following packages:
Extreme (LLU - C&W)
Pro (LLU - TTB)
I understand that these providers are offering the same upload/download speeds as each other, though the upload will be about 30% slower than the O2W package I currently have. The differences therefore relate to the underlying network infrastructure provided by C&W/TTB and the amount of control available to XILO.
Does anyone have any first hand experience of C&W/TTB? I guess I am looking for some techie-insider information about which might be the best choice.
