On Tuesday morning I'm going to switch the OpenStack Keystone token engine from UUID tokens to fernet tokens[0].  The changeover[1] will be abrupt and cause all existing sessions to reset (e.g. if you're using Horizon you'll have to log back in, and if you're in the middle of creating a VM that creation will probably fail.)  Should you encounter this interruption, just try again in a few minutes and everything should be fine. The new tokens will generally behave the same from a user standpoint, but will allow us to simplify and modernize things on our end a bit. The switch will happen at 15:00 UTC on this Tuesday, 2020-02-18. That's 7AM, Pacific Coast time.
