it is sort of funny to see this on a post submitted by a gitbook user that starts off by saying "We have yet to see any official customer communication or breach notification.", and where the company's status page (https://www.gitbookstatus.com/incidents/01M6FXDDGQRWHMYYWXY2...) doesn't mention the customer data that was potentially accessed by the attackers or mention that credentials/tokens should be rotated.

in fact, that status page (which is linked to at the top of the gitbook site) still says "You don’t need to do anything right now."
