There is since 2 weeks an intermittent DNSSEC failure on DashNinja.pl domain (no idea why as everything is configured correctly and worked for years). This result in the website been not accessible if you DNS resolver checks for DNSSEC validation (they should...).
Trying to fix that problem on dashninja.pl (it will take at least 48h, restarting the OpenDNSSEC config from scratch), in the meantime you can :
1) disable DNSSEC verification (if you have a local bind allowing that) - Not recommended
2) use TOR v2 : http://seuhd5sihasshuqh.onion/masternodes.html
3) use TOR v3 : http://dtsfpvtrnqcyordz62efdrvhevgmqvpi5ora2nul7c2wikjxw5kboeqd.onion/masternodes.html
4) use I2P : http://dzjzoefy7fx57h5xkdknikvfv3ckbxu2bx5wryn6taud343g2jma.b32.i2p/masternodes.html (or http://dashninja.i2p/masternodes.html if you put it in your adress book)
5) use the alternative URL (HTTPS too, same server, just using a subdomain of my personal domain) : https://dashninja.elbereth.zone/
