"Anyone stuck at the word "GO" when attacking specific gyms?"

#PokemonGO: So my pokemon is stuck on a gym at the moment and everyone in my community who tries to take it down are stuck after clicking go battle, nothing happens at the word "GO" fades, and are unable to reach to the battle screen, some gets network error (2) if waited long enough. those who restart the game get the error "Failed to get game data from the server"​Meanwhile a friend of mine in another area tried to attack a totally different gym and encountered a similar error.​Also anyone have any ideas how to fix it?​EDIT: I should mention, only specific gyms, many other gyms are totally fine. via /r/TheSilphRoad http://bit.ly/2Qq5Vya
