If a new website has launched but you can still see the old version, it does not always mean the launch has failed. Caching and DNS changes can cause different people or devices to see different versions for a while.
Common reasons the old website is still showing
- DNS propagation: some networks may still be using the previous DNS information.
- Browser cache: your browser may have stored parts of the old site.
- Device or network cache: another device or Wi-Fi network may be using older information.
- ISP DNS caching: your internet provider may not yet have refreshed the DNS response it is using.
- Old DNS destination: the domain may still be pointing to the previous website host.
What can I safely check?
- Refresh the page and, if appropriate, try a private/incognito browser window.
- Compare another device or network, such as mobile data instead of Wi-Fi.
- Confirm the exact domain you are testing, including whether you are using
www. - Allow the expected DNS update period if a recent change has been made.
See what DNS propagation means and how long DNS changes can take.
What if the domain is still pointing to the previous host?
If everybody continues to see the old site after the reasonable update period, the DNS settings may still direct the relevant hostname to the previous service. Check the DNS change against the instructions supplied for the launch rather than guessing a new value.
If you cannot find the controls, see how to find your DNS settings.
What should I avoid doing?
Do not: delete DNS records, change nameservers repeatedly or copy settings from another domain simply because the old site is still visible. Those changes can affect the website, email or other services and can reset the troubleshooting process.
