Unfortunately, that sounds like a change your employer or their firewall app has made. It sounds like they have chosen to categorize all of wikia.com as a 'games' site, and thus it has become blocked.

I don't think it's something we could change on our side - but you could appeal to your manager about this issue, to see if they can make any tweaks.
