I've found latency in the UK can be about a third lower than Ireland. I used Bytemark for testing in my recent book but Azure have UK regions now [0] and DO have had a London DC for a couple of years [1]. AWS UK is currently just "coming soon" [2] but Werner has said "end of 2016 (or early 2017)" [3].

I expect Microsoft are using the UN region names for Europe, where Britain are Ireland are part of Northern Europe.

Nice find! That probably explains it.

The UK names still aren't great, even if they sound reasonable in isolation (Cardiff - West, London - South). They have fixed the map though.
