Plusnet to EE migration - is hosted domain storage transferred?

[#1]

If I go with the enforced migration to EE in order to keep my landline phone number (and I think I'm generally ok with that)   what happens to my little web site hosted by PN for the last 19 years?  Does that transfer over to EE (I've not checked whether EE offer web hosting)  or will it vanish? What about the domain name registration (I think that incurs a small yearly fee)?

It's not a big deal in the great scheme of things (just a few page and images I published years ago), just curious as to its likely fate?

It'll also be interesting to see what happens to my plusnet mailboxes, though they're pretty much defunct now.

By hosted do you mean www. userid. plus .com or along the
lines of mydomain.co.uk

Both would eventually migrated to greenby but if that doesnt happen before you move to EE or any other ISP then the former wil be lost. As to the latter that would be interesting as plusnet are the registrar so not sure what happens there.

Yeah hosted on plusnet / force9 servers but with my own .org.uk domain name registered and routed to it.

@ntpntpntp If you move to EE , your Plusnet account will close and you would lose the hosting ( both webspace & email ) for your domain. In addition you would lose the native <account>.plus.com email & webspace. 

In you situation I'd look into remaining with Plusnet on a broadband only (FTTP or SoGEA) product, and migrating your phone number to a third party voip supplier.
