What happened to Coinbase GDAX?

Has anyone heard any updates regarding Coinbase's GDAX platform? I've noticed a lot of chatter in the crypto community about some potential issues or changes. Could you elaborate on what's been happening? I've heard rumors of technical difficulties, security breaches, or even a potential rebrand. Are these rumors true? What impact, if any, has this had on users and their trades? Have there been any official statements or explanations from Coinbase regarding these matters? And if so, what do they mean for the future of GDAX and Coinbase as a whole?
