Crunchyroll previously reported about how Girls und Panzer der Film would receive limited 4DX film screenings (featuring added effects such as vibration, wind, smoke, and scents to create a more immersive viewing experience) at some 30 theaters in Japan beginning February 20, 2016.

Now it appears that the popularity of cute girls and the tanks that they pilot was too much for the servers of the United Cinemas Group to handle. Within moments of the tickets going on sale, frustrated fans were already flocking to Twitter to protest their inability to purchase tickets due to the servers being overloaded by the surge in web traffic.

In other Girls und Panzer news, sharp-eyed fans have observed that some theaters have been using the "ガルパンはいいぞ" / "Garupan wa Iizo" ("Girls und Panzer is really good!") meme to advertise the 4DX screenings of the film:

Truly, the combination of tanks, moe, and Tsutomu Mizushima's direction is too powerful to resist.
