Old IPad Trouble

I cannot seem to activate my old iPad. It keeps coming up with an error saying, “Your iPad could not be activated because the activation server is temporarily unavailable. Try connecting your iPad to iTunes to activate it, or try again in a couple of minutes. If this problem persists, contact Apple Support at apple.com/support.” I have tried pressing “try again” several times. It is connected to the WIFI and I tried pressing “connect to iTunes” but it still gave me the error. I have also tried turning it off and back on. I’m not sure what generation iPad this is, but it is pretty old and hasn’t been used in a long time.
