Time: around 4 EST, 8/31
Frequency: I've had 90k errors before (hasn't everyone?) but they generally get cleared up after a maintenance
World name: Hyperion
Character name: Arduin Tyr
Class/Level: White Mage / 50
Party or solo: Relic Duty fight in drybone area to kill Hydra
Area and coordinates: South of Drybone, in a Duty instance

Steps:
1. We had just won a relic hydra fight (winning isn't the issue, we had one another half an hour before) and the entire party was loading out of the duty instace.
2. Instead of loading us back into drybone, the party was given 90k errors and kicked offline.
3. Attempting to log back online has caused repeated 2002 errors, resulting in our ability to log back in. This is occurring for multiple members of the party, 2 of which were in my FC and I know they are experiencing the same issue.
4. I have followed all the steps in the sticky'd post about 2002 errors, which suggests the problem with that error is the users connection or router, it was not fixed by completing those steps. That information is clearly incorrect, this error is related to the 90k error just like the 10102 error is often a cause of a 90k while loading.
