This should be resolved now.
If you still have any queries, our staff is now handling them in the ticket system. I'm sorry for being slow, but all our manpower has been allocated to handling the main issue.
@matsta - the IP range was blocked by the datacenter due to the whole network being listed in Spamhaus. This is not anything unusual, as we don't own the datacenter where Shared3 is located.
To those on Shared3 who were affected - please e-mail info [ at ] rmxhost.com and ask for the next 3 months free.
To those who use Cloudflare for their DNS, please update your nameservers to ns1.rmxhost.com and ns2.rmxhost.com for now.
Again, I apologize for this. We're not perfect, but we're always working to get better.
