This is the link to the post. It says the announcement was made by email, so all kraken users should have had a full copy of the message emailed to them. The full announcement is longer than what Restyler quoted.
https://www.xrpchat.com/topic/14733-kraken-withdrawal-time/?tab=comments#comment-160253The last bit of the announcement says that even after January 4th they will be slower than normal to process deposit/withdrawals.
Finally, we are anticipating a surge in the number of deposit/withdrawal applications on January 4th, so please be aware that it may take slightly longer than usual for some funding applications to be processed.
