Is BT DNS down?

CanardNoir — Wed, 29 Oct 2025 17:21:38 GMT

The only way I can get internet access is via 8.8.8.8 as my DNS.

The BT DNS seems not to be working.

Why can't I get to microsoft support site from my BT broadband connection?

Attempting to get to the microsoft support site comes back with an "unable to connect" page (generated locally) suggesting a DNS problem.

I've tried flushing using ipconfig and restarted the PC - same problem.

Most of BT seems to be down so wouldn’t surprise me.

I can confirm that the “My BT” app is down. Also on down detector there’s over a thousand reports in the last hour (baseline is 25)

Looks like the service status page is also down.

It says it can't find my phone number.

I get that too.

Infuriatingly most of us have done away with our landlines which leaves us no way of checking the service status anyway as it requires a landline number.

Honestly I wonder if any of their staff have ever tried to use their systems

You're probably not missing anything.

They never say they have a problem especially when they do.

It's only by asking other customers (like here) that you find out it's not a local problem with your own PC or phone.

There is no understanding of (or care for) customers - no idea why. Perhaps it costs too much to care.

🔍 Current Status:
• BT DNS problems are being flagged by users across the UK, including in areas like London, Manchester, and Birmingham.
• The spike in reports suggests intermittent connectivity issues, likely linked to DNS servers not resolving domains properly.
• Some users are unable to access websites unless they switch to alternative DNS providers like Google DNS (8.8.8.8) or Cloudflare (1.1.1.1).

🛠️ What You Can Do:
• Change your DNS settings manually to a public DNS provider. This often bypasses the issue:
• Google DNS: 8.8.8.8 and 8.8.4.4
• Cloudflare DNS: 1.1.1.1 and 1.0.0.1

• Flush your DNS cache:
• On Windows: Open Command Prompt and type ipconfig/flushdns

When can I expect a paycheque from the Customer Service Department?

Of course you are just telling the people who already know how to change their DNS as they will be the only people to see it.

Alternate DNS: 8.8.4.4 (Google) or 1.0.0.1 (Cloudflare)
Click Save

(Optional) Flush DNS Cache

Press , type , then press Enter
In Command Prompt, type: and hit Enter

Quad9 DNS @ 9.9.9.9 is another DNS resolver that is worth a punt too. I use it all the time, no issues.

This issue began yesterday afternoon and continues this morning. BT's DNS isn't reachable and since there is no way to modify the DNS address on the SH2 it has to be done individually on each device to something that works (eg 8.8.8.8). This includes PC, mobile phone, SkyQ, Alexa etc. Restarting the SH2 this morning does not make any difference (no reason why it should since the problem is within BT's infrastructure not mine).

There is no acknowledgment of the problem on BT's service status page (as usual) yet it continues (for about 16 hours so far). I wonder if anyone else knows any more about this issue.

Eventually managed to talk to someone at BT.

After asking me to clear my browser cache and disable the Windows 11 firewall (neither of which would have resolved a problem further down the IP stack, they told me to do a pinhole reset of the hub.

That seems to have sorted the problem.

@CanardNoir Not a practical solution for many and I entirely understand why most people wouldn’t want to spend money on something that an ISP supplies as part of a contract, but this is why I wont use an ISP router and why I choose my own DNS resolver.
