Niantic disabling Pokemon GO gyms for "remodeling"

Heads Up: Gyms will soon be closing temporarily for remodeling. Any Pokémon you've assigned to Gyms will be returned to you at that time.

As we get ready to update Pokémon GO, we want to ensure that Trainers have a sufficient heads up that Gyms will soon be disabled so that they can collect their Defender bonus. We will provide updates on our social channels in advance of Gyms closing in-game.

Looks like those big updates teased for the Summer are already underway. No word on how long gyms will be down for, but it should be interesting when they return!
