It can certainly be an issue on the end of the server that handles Odyssey specifically. You really can't rule anything out, anything network related you should always, always do these things no matter how sure you might be that it isn't the problem. There's no valid reason NOT to do it, even though it is *almost* certainly a processing issue on the server and probably not a networking issue. A whole bunch of people submitting completely normal ping and traceroute results should clue them in to this assuming that's the case. So understand that even though the problem probably isn't a connection issue, submitting the data will still push them in the right direction.Ping and Tracert commands sadly won't be much help when it comes to troubleshooting this particular issue, as there is nothing wrong with Client to Server connection. Most these can do is allow SE to ping player machines on their end in order to investigate connectivity issues.
As for the post above, the quote contains an EU site URL, and they refer to the "Square Enix Support Centre," which uses the EU spelling of what in US English would be "Center." I don't see the bug here.
