March 7: Sydney WireGuard outages from upstream UDP filtering (14:39UTC)

WireGuard connectivity in our Sydney region intermittently failed because an upstream network backbone was dropping/filtering UDP traffic. This caused 6PN private networking to fail between Sydney and other regions, as well as some internal services to become degraded, until the upstream issue was corrected; service returned to normal within minutes once the filtering stopped.
