I have checked it and it gives me some warnings.
1. TLD Parent Check WARNING: Looks like the parent servers do not have information for your TLD when asked. This is ok but can be confusing.
2.SOA EXPIRE Your SOA EXPIRE number is: 100. That is NOT OK
3.Reverse MX A records (PTR) ERROR: No reverse DNS (PTR) entries. The problem MX records are:
188.8.131.52.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips
The 1st 2 are warnings that I never had before but my domain was reachable for more than a year and the last one (ptr record) is something that I had for 3 years now.
The strange thing is that I cannot even ping my domain but my emails work and in any dns toolbox is recognised and analysed.
If you can please try to browse at www.occhio.com.cy
and let me know if you can reach it. otherwise let me know what can I check to find out if anything concerning my setup has been broken since the upgrades.
