iOS 8 update fails with network connection time out I am attempting to update my iPod touch 5th generation to iOS 8 but I am unable to do so.

When attempting to update over-the-air, I do not get very far into the updating process (still in the downloading phase) when a message pops up stating that the update failed (providing no reason).

I have also tried to update through iTunes 11.4 on my computer, however a message pops up stating that the network connection has timed out.

Are Apple's servers overwhelmed, or am I doing something wrong? I am unsure what to try next.
One known condition for the install is that the device must have ~5GB free space for the temporary download of the installer file. You should delete unused apps, music and photos/movies from your iPod before you run the installation. The iPod should give you an error message saying the device doesn't have enough room.
