Seems it is. Can't buy anything in-world that uses Caspervend.
We have tried pinging Caspervend website using our server and the website returned the above results. If caspervend.casperdns.com is down for us too there is nothing you can do except waiting. Probably the server is overloaded, down or unreachable because of a network problem, outage or a website maintenance is in progress...
It would be more helpful, if the word would be spread to all people being affected, not just to a few selected ones.
When i tried to get a redelivery 11 hours ago, i just got to see a timed out connection. And that didnt change until now.
Its not rocket science to set up a status site for anyone to read stranding there. In case the whole domain/hardware/rack/datacenter is broken, then just redirect it to a backup where some infos are displayed.
