Did the leaves fall off? Something not working right? Let us know how we can improve the Photosynth experience.
At first I'm French, so sorry for my English !
In fact it's a part of Microsoft ICE (imagine composite editor) which doesn't work, I make the panorama, it work perfectly, but when I click on "Publish to the Web" a popup appeared which said "The photosynth service is not available. Please try again later" ... and it's like that since the begining (several day), not just today !
It's probably not a problem with my firewall because i've tried to put it of and it's the same thing
Are you able to create a synth with the Photosynth app for Windows? See if you still get this 'service is not available' message when you're not uploading and ICE panorama.
