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?

  • You said they reset the cable modem, but if they have a separate router (likely serving up wifi) they should power cycle it (not reset it as that will dump the config). – perry Oct 24 '14 at 15:17
  • Yes, I meant rebooted, not reset, and their modem/router are one and the same in this case. – Laryn - CEDC.org Oct 24 '14 at 15:23

Try:

  • restarting your web server
  • clear your cache and the one of the people having trouble
  • flush your DNS cache and the one of the people having trouble
  • eventually, restart your DNS server
  • reset your .htaccess file
  • check if you have misconfigured something in your server
  • check your firewall rules
  • try changing the home IP address if you have a static one
  • eventually, try changing your IP address
  • eventually, move from ISP that provides internet at home

(Are you using a VPN?)

After much pulling-out-of-hair, I got this message today:

I logged into my router to check the DNS settings like we discussed. I just happened to click on security and noticed the "firewall" box was checked. I un-checked the box, clicked save, opened a new tab and entered our domain. Eureka! our site opened right up! It was my router.

  • +1, good to see it's fixed (even though it's almost a year later). – William Edwards Aug 14 '15 at 15:57
