EDIT:
1. I'm planning on consolidating the pool instances into one now that the broken stratum implementations should be able to mine on the main pool. I will run the main pool on both ports (3333/3334) so that people won't need to change their miner settings, but the pool stats for the "tube" pool will simply point back to the same stats as the main pool. I'll keep all the existing links also but suggest that anyone starting up new miners or workers point them to the default location: solo.ckpool.org:3333 . I'm also adding port 443 as an option so now ports 3333,3334 and 443 will all work.
2. In addition, I'm going to give advance warning that I will be taking down the testnet pool in one month's time when the paid subscription for that VPS expires. I can't justify running the pool for free when people happily mine on it and don't donate anything (no I'm not interested in testnet coin donations). So unless someone has a burning need for this service and is happy to donate a few decibitcoins to keep it running, I will shut it down.
3. The provider for the main pool has a scheduled hardware upgrade planned for December 4th at 7:00:00 AM UTC. Due to the timing of the upgrade and timezone differences, and the planned downtime on their end, the pool will be effectively down for maintenance for at least an hour, so expect a period of outage at that time. I will endeavour to keep the downtime as short as possible
EDIT: The changeover described in (1) above is now complete.
Please tell me if you are unable to mine on the default pool now, thanks.
