DNS related stuff. I have a client with multiple websites with me. 2 of them were inaccessible by support staff in India. Tested the DNS and there was no propagation in India and a few other locations. Spoke to their IT guy and he said some countries were blocked from the DNS level. Also said both domains use the same DNS.
He removed the block for India. Great. Now one domain works and the other still not working. His conclusion is the problem is from elsewhere and he can’t do anything about it….
