On Monday my hosting service moved their servers. Ever since then requests on my site for URLs not ending in a backslash forward to
crazedmonkey.nfshost.com. This means that if you access my transit map without including the backslash, the map will refuse to load because of inconsistencies with the Google Maps API key. I’ve opened a related ticket with my hosting service and hopefully they’ll fix the issue. In the meantime, please use the URL which works.
