Some bridges don't have a valid status page
@gk found a bridge that doesn't have a valid status page, but it does show up in the extra info files that rdsys is using.

I've verified the bridge is in the extrainfo file. So rdsys seems to be throwing it out for some reason? If the bridge doesn't work, it should show up as dysfunctional but still be saved as a valid resource.
