Ouch.  that is the worst server to have fail.  Hopefully your replication and backup was setup well.  My strandvision.com digital signage system has 3 dedicated servers spread around the country running for over 14 years now, so if you want to share horror stories / advice, let me know.

Oliver, if you are interested, I can put an email alert into minergain.com so you can be notified when the site cannot be reached and another when it recovers.  It is down now for me (minergain) with a couple of IP addresses of our 32 available.  It is interesting that the feedback.coinfoundry.org is working though.  Not sure if we are banned or if you are having other issues.  I just need your email address to get that activated for you.

Hi there.  I am creating a site called minergain.com and used to have poolmining.org listed.  Since your home page does not function at all (spins for about a minute then dies with no content delivered), the minergain system automatically removed the coins that can be mined from the site. 

It looks like your dns entries are pointing to cloudflare and I suspect that your opted not to pay for that (understandable).  I am working on changing all the entries in my system to use the new domain, but as an fyi, you are probably losing a lot of potential new miners since the web has many places with your old site.  I would recommend that you get your dns setup properly and do a 301 permanent forward in your .htaccess file.
