I've just helped move a site from one server to another and updated the DNS servers and settings as well. It's been a month or more since the DNS changes, and has been working fine for almost everyone -- I have reports from 2 or 3 people that they can't access the site from home. ("This webpage is not available")
- They don't use the same provider -- one has Comcast and one has Brighthouse. However, the one with Comcast at home also uses Comcast at the office and it works at the office.
- A computer that can't access at their home can access from the office, so it's not the computer. A phone with Wifi enabled can't access it, but can access it immediately when Wifi is turned off.
- They've reset the cable modem already.
I'm stumped! Any ideas?
