opencyclemap tiles mysteriously quit working

I’ve been using qlandkartegt to manage GPS tracks and waypoints lately and I’ve noticed that in the past week or so the opencyclemap tiling no longer works.

They had some obscure URL listed as <andy.sandbox.cloudmade.com/tiles/cycle/%1/%2/%3.png> but another obscure online document mentioned using <tile.opencyclemap.org/cycle/%1/%2/%3.png>. Up until recently it DID work with the original URL. Right now neither URL return any map tile data.

What gives?

Only OpenStreetMap is still working for me. Any suggestion?
