sbiddle: Being on an ISAM there is very little chance of being port waiters in the area. The fact all of Whitby has UFB would make this even less likely.
As pointed out though a transition won't disconnect the broadband, merely move it between providers, so there is no chance of losing the connection.
Sorry to hijack this, but Whitby has UFB already? Am moving their in April and the Chorus maps says it's not due till Sep 2015. None of the ISP's list Whitby as having UFB available yet (that I can see).
Do you know something extra :-)
