I am aware of that mate, but when Axxess had their authentication issues over the last few months, Afrihost didn't. These DNS and authentication issues are way too common on the MTN network. Time they sort this out once and for all. You try explaining to complete Noobs how to update their dns address, then multiply that by the number of employees you have to do that for.
