Captains, server issues and issues not directly related to the server (thus cannot be fixed on our side) can be checked very easy: the first ones affects all players, the others only affect certain group of players (if their server characters have no issues, we cannot help further). As an example - players from Thailand had some major issues playing on EU PVP (the only solution was to use VPN) server not long ago, but it was mysterious solved just as it started.
Based on server logs there were no issues on Saturday with PVP Global server.
Do you have an option to temporary test the game through another source of internet like mobile connection or from different ISP? You could also test the game via VPN connection.
