Geo locate change for IP ?

[JASON BOTHE via NANOG <nanog () nanog org>]

Hi guys

Something odd has happened and I’m not sure how to sort. One of our public prefixes, 205.174.3.0/24 issued from ARIN 
has suddenly had its geo changed and now everyone accessing the internet from it is showing up as a UK IP, London 
specifically. We announce this and every other prefix we have out all of our peers globally and are pretty mystified on 
how this happened and how to resolve. Any help is appreciated. 

Thanks

Jason
