DNS / Email urgent Help Please
Hi Guy,
I changed my DNS provider/records from Memset to 123-reg - this was done on 17/3/2015 2days ago.. I am finding that over 3G/4G connection (iPhone 02 / dongle) and some other LAN connections I can not even ping the A records it is very intermittent I get "ping request could not find host.... please check name try again"- soon as I switch to WIFI it all works fine.. example of one my A record is mail.mydomain.co.uk.. everything internally works a treat..it was all working fine only until I switched over DNS provider...the DNS records are all setup fine... Has anyone got any ideas what might be causing this?

What was the ttl set on the DNS records with the old provider? Maybe the old provider is still in cache at some public DNS servers which might cause intermittent results...

my real IP is: 81.168.127.145 (this has my x3 A records) / and my web-hosting is: 23.229.142.233 ( I have setup x2 A records with "www" and "@" for this IP) I have no other A records or CNAME records in my DNS. My email is hosted with hosted email security with 3rd party....
Do you think everything from my end is ok?

Yes it all looks fine. Looking on http://centralops.net/ all your dns names resolve to the correct address. Depending on the wireless carrier they may be blocking or not allowing or limiting ICMP (Ping).
I get no dropped packets from here in good old Charleston, South Carolina, USA.
I think you should be good.

could certain networks take more time to register these DNS changes??
Yes, it can take upto maybe 72 hours or more before all public DNS servers get the new records, and if the previous TTL was high enough it can sometimes take even longer.

Guys - an update - think this is the issue.. basically as Godaddy is hosting my website abmcatering.co.uk - they also have records with Mail / autodiscover - and MX records.. I changed the MX records to my server and it works fine... I deleted the autodiscover record from godaddy and works now.... can I remove all these MX records and mail records from here as I am using 123-reg to manage my DNS??

basically I used 123-reg for all my domain DNS records (MX / mail / A records) / godaddy is ONLY for webhosting - but this had records such as mail and mx record details - im guessing all these records can be deleted ? except the web hosting records...

Thanks for the reply - I was thinking to delete all the MX and A records from GoDaddy and just keep the Web-Hosting records that are required... as 123-Reg is managing all my DNS records...this would be ok right?
