In my opinion, the only way to fix this issue is to increase the capacity of asian (especially hong kong) server’s capacity, however this is very expensive. hopefully the re-release of Australian servers as promised in RDC 2021 can help mitigate the issue.
If you know what you are doing you may also enable the fast flag “EarlyExitIfHang_DataCenterFilter” to block the portland servers as a temporary fix. – incorrect
