Sorry for the delay.
This includes ramble.i2p, rss.i2p and tube.i2p (which was up most the time).
I had been having some issues with the router that serves the http tunnels to the sites and had sporadically implemented random little fixes that worked for a bit, but for the better part of this last week most of these have been down on the network and I've been too busy to sit down and rebuild the server.
Should all be back up and stay up now. Sorry for those who have PMed me or pinged me in IRC. "I know, just use the .onion site for now" is no longer my answer haha.
