There is an ongoing DDoS attack on Namecheap, a DNS provider that was hosting all entries for vrchost.com. This has caused domain lookups to vrchost.com domains to fail, so that those web sites were not reachable.
We have moved all our DNS records to another provider, but due to caching of the old information in different places on the Internet, web sites may continue to be unreachable to you for the next few hours.
We apologize for any inconvenience this is causing. The actual sites are all up and running, which of course is not helping those who cannot reach them.
