To whom it may concern: It appears that cdn.visiblemeasures.com moved to Internap at some point (bucket = vmc.http.internapcdn.net according to CNAME). This causes it no longer to work, and coverage of the entire domain needs to be removed as far as I know.
I haven't yet checked the possibility that this domain rotates between different CDN providers over time and/or region. Of course, if any one of them is broken, then this is a real problem. For examples of content broken by this, see the videos on Dorkly, e.g. http://www.dorkly.com/video/58741/yoshi-isnt-allowed-in-the-castle (the offending request is a Flash subrequest, something to do with ads/tracking).
