Christie "Kiara" Renzetti, EQII Community Manager, just let us know that SOE is having network issues. This is affecting login servers, forums, chat, and 'most everything.
It's being worked on and will be resolved at fast as possible.
UPDATE: Craig "Grimwell" Dalrymple tells me the the problems are now resolved.
FURTHER UPDATE: Kirstie posted on the official forums that the login servers are still having issues, but they've isolated the problem and are working on it.
