Re: [Bitcoin-development] DNS seeds unstable
My android wallet is working OK. Yes it isn't great when seeds have temporary availability problems but things are still working. There's a couple of pull reqs outstanding to include hard coded seed peers and getaddr sourced IPs. Once those are finished and merged in there'll be more backup paths.

Re: [Bitcoin-development] DNS seeds unstable
Hi guys Just wanted to let you know that Andreas' testnet Bitcoin Wallet doesn't work because of fail in the peer discovery, and this caused us problems as we cannot properly demonstrate my XBTerminal POS on the Bitcoin Conference. Right now I'm booting up an own full node that I will set as trusted peer in the Wallet settings, hopefully this will work. However this DNS discovery problem is really a problem, even for testnet. Btw, I had problems firing up the full bitcoind node also, of the same reason - discovery failed. I had to ask Andreas to paste me his node list to manually seed the nodelist. So I've set up and will run a well connected testnet node, as we need it for the XBTerminal. Please let me know if I can somehow help to fix the DNS discovery issue also.
