The domain name is question: cleangreenpgh.com.
I host a few web client websites on my co-located Mac server. Domains are through OpenSRS. Four domains in all, using same records to point to respective websites on co-lo'ed Mac, all working over the past several months without issue until I received an email about the above mentioned website not resolving.
Sites such as mxtoolbox, any dns or 'a' record searches all come up as 'no records found' though the settings in my OpenSRS panel are correct - that is to say the other three domains / websites are resolving normally.
NS for cleangreenpgh.com are set to dns(1,2,3).systemdns.com. A records created to point cleangreenpgh.com to 188.8.131.52.
=============== UPDATE / ADDITIONAL INFO =================
Thank you for the replies.
The domain was renewed on Feb 8, I did the renewal myself and have all of the records. In fact, my openSRS panel shows this info...

I'd post a screenshot, but I don't have the reputation for such.
As for receiving negative post ratings - I realize that 98% of these types of questions are due to a lack of even the most trivial of networking knowledge. But why give a negitive rating way before the question is even concluded? Is there an "authority" on positive / negative ratings? Someone who has a final say... or can anyone who looks at the post just assume I am an idiot and give a negative rating before getting through to the end of line two? I have followed the guidelines offered on the "How to Ask" page. It's a deterrent to read the post.
