I don't have any solid information with regards to this yet - but for those that cannot access Etsy, neither can I. And I suspect it is a major downtime that the team did not had the chance to make it an announcement, I am sure they are working on their best to at least tell Etsians what's going on.
You can click Unofficial Update Site for some update.
I hope this isn't a disaster of any form, I am sure the Etsy technical support team will try their best to recover and resume the services soon. :)
UPDATE: Etsy services resumed
