Unable to download patch or log in to Lodestone

[Verence]

Platform: PC

When attempting to download the patch today, one of two things happens:

First, the download goes a short way in, stops, then gives the following message
"The server is not responding.
For assistance with this issue, please visit the SQUARE ENIX Support Center.
https://sqex.to/x4w
[30413][10009][10019]"

Second, the download never commences and the following message displays:
"Unable to complete version check.
[30410][30607][10009][1019]"

Attempting to log in to Lodestone to report this issue to support results in one of three things happening:

First, the page times out when attempting to authenticate my token code.
Second, a site error page is displayed with a link to the main SE site.
Third, a select character screen appears claiming no characters are linked to my service account and prompts me to log out.

To resolve this issue I flushed my DNS, refreshed my IP, rebooted my modem and router, and attempted access with a VPN active. Nothing has fixed the issue, as it seems highly specific to the XIV game servers and the Lodestone site only. Everything else works perfectly fine.
