Connecting to wrong server

over the last month i have been connected to the wrong server. I am in Australia and normally have 8 ping i used the in game diagnostic (Ctrl+Shift+N) and discovered i was no longer being connected to Sydney server but now Singapore (pse1) i have run a windows MTR test to confirm. I have contacted Overwatch Support through live chat but they were of no use telling me to do the stock standard turn off and on again stuff. Hopefully someone else out there has a solution out there to my problem.
