I think this bug is back. I just tested two of my domains celiac.com and glutenfreemall.com and and getting the same warn issue, but my serial number are correct:
WARN | SOA field check | One or more SOA fields are outside recommended ranges. Values that are out of specifications could cause delays in record updates or unnecessary network traffic. The SOA fields out of range are: serial | 2013011702 | SERIAL - we check that your serial number matches the recommended format found inRFC1912 section 2.2. |
