According to whois, a change was made to your DNS today. When did you add the A record for www.btgmaslak.com? If it was just today then you just have to wait for things to propagate - can take up to 48 hours and sometimes even 72.
The domain checks out OK using online DNS tools. The only noteworthy warning was:
It seems you don't have MX records. This means that all the emails sent to your domain will be sent to the A record of your domain (if present), accordingly to RFC 2821 section "5. Address Resolution and Mail Handling".

DNS does not update instantaneously and your regions DNS servers may be taking longer to update than google or OpenDNS. If you made changes within the last 24h, it's likely that it simply hasn't propogated to the regional DNS yet. In which case, you have to wait.
