This may not be specifically related to Cesium but I am encountering a problem within Safari 7.0.1 that seems to affect not just Doarama but other demos listed on cesiumjs.org. It may be present in other versions of Safari but I haven’t been able to check.
It appears that Safari is having trouble with cross-origin resource sharing (CORS). Doarama uses terrain information provided by cesiumjs.org and it is these requests that appear to be failing. On closer inspection however, the requests seem successful (200) but the method is OPTIONS. Shouldn’t it be GET? Either way I am a bit stumped by this issue as it is only encountered in Safari. Chrome and Firefox work just fine. I was wondering if anyone could offer me some advice, perhaps someone else here has encountered this?
I’ve included some screenshots to clarify this a bit further. Let me know if require any more details.
