I have had a similar problem with the Australia site (as I'm from Australia and I play on the PC). If I select another server cause I can't find a game on the Australian Server, after I exit the game on the other server, my default ping server is often pointing at the Unioted Arab Emirate which has the highest ping for me (470+ ms).
I seem to have found a work around which (so far) has fixed my problem. You may want to see if it does it for you. Read this post - https://answers.ea.com/t5/Bug-Reports/Starfighter-Heroes-Update-Changed-Default-Ping-Site-to-Worst/m-p/6908971#M17539
My other post in that thread at least has identified what game file seems to be causing the problem and where it is located.
Hope that is of some help to people.
I'm on PS4 and keep getting mine reset to Ireland 25ms should be on UK 14ms.
@mrLionking17, @New_Roosterman's work around works for PS4 but you need to search for your game 1st then go to the EA accounts set your ping site and then sit in the EA accounts screen without backing out, as long as it finds a game it should reset your ping site to Australia.
