Is O2 down for everyone or just me?
We checked o2.co.uk directly from our server and it responded successfully. That means the site itself is up. If it isn't loading for you, the cause is most likely local — your internet connection, DNS settings, browser cache, or a network or firewall block.
What to try if it still won’t load
- Reload the page, or open it in a private/incognito window.
- Clear your browser cache or try a different browser or device.
- Switch networks (e.g. mobile data) to rule out your connection or DNS.
- Flush your DNS cache or try a public resolver (1.1.1.1 / 8.8.8.8).
