Cloudant still has a free offering and kindly offered to support
kan.so - however, I didn't have much time available and it was easier
to migrate the couchapp setup to a vanilla couchdb install. Since I
already run a VM with couchdb for the
http://jamjs.org site (which
seems to have no problems with uptime) I just replicated it there and
switched the domains over. CouchApps are so awesome ;)
RE: Iriscouch - Jason and Iriscouch have been super supportive of this
project and my thanks goes out to them. Sometimes instances were
unavailable or took a while to start up but it did mean that Iriscouch
were able to host lots of couchdb instances for free, so it was a
great service to the community. However, since being acquired by
Nodejitsu, Iriscouch availability has increasingly become a problem.
No doubt in part because Jason Smith is no longer at Nodejitsu.
Hopefully we'll see another CouchDB hosting company spring up in the
future to fill this gap.
