You have any 2.4 GHz WiFi problems? In theory there is a problem, and I know a dude with a lot of ZigBee and a lot of 2.4GHz problems, but without going over with work equipment and spending some time doing work for free, I can’t be sure it’s ZigBee. It’s just my best guess.
You already married to ZigBee? If not, maybe don’t. It causes 2.4Ghz interference. You’ll need to think about WiFi channels and avoid ones that overlap with ZigBee. Either that, or use 5Ghz WiFi and repeaters to make up for the lower penertration (if an issue).
I can only speak of on Linux. If you know the disk is bad, clone it, with ddrescue, and fix the clone. But in future RAID and backup remotely. Also, next gen filesystems like ZFS and Btrfs for check sums and self healing and subvolumes with send/receive deltas between them.
Also depends on the country. It isn’t everywhere. Non-commercial file-sharing is legal in a number of European countries and I’m sure elsewhere.
It could be taken as a sign of the health of the democracy’s function and technically literacy of the population. In a society of tech heads with a highly functional democracy, it would be DRM measures that would be illegal…
Just a follow up to this.
So I never ended up contacting O2 to say “please stop this”, I just used Wireguard to home and ignored it. Until the local Morrison’s wifi started doing the same thing but worse and I couldn’t event Wireguard round it.
So I finally just bought a domain and setup my Apache to redirect the old duckdns to the new domain.
So far this all seams to be working great.
Yer, I used Rethink DNS in F-Droid to test this already. Basically it’s fine when the DNS is encrypted.
Edit: I was wrong. It was just working again generally.Even with DoH DNS, I still see “Access denied” going to duckdns.org and my sites still don’t work. Direct IP works. Not sure how this block is working yet.
I’ve tried it with F-Droid’s Rethink DNS already and everything is fine then.
Pretty sure they are doing DNS packet inspection. If the DNS is to duckdns (and no doubt other Dynamic DNS), then port 80 has their block page, and not sure what they are doing with 443, but it’s not accepted.
Boringly, it’s not being messed with right now. It’s done this before. Coming and going. It’s one of the things that stopped me working it out before.

I tried their help chat bot and it just said to install their app after a few exchanges. My phone is de-googled, so good chance their app won’t work. Plus, I avoid installing closed apps as it is unhygienic. Each one seams to demand access to contacts and location and won’t work if you deny it. Dystopian present, let alone future.
Pretty sure they are working via DNS packet inspection.
It’s not the DNS server. I’m sure of this because Termux uses a different DNS server but does the same. I also tried setting my phone to use OpenDNS directly. I’m pretty sure they are inspecting the DNS traffic. Exactly so changing DNS server doesn’t help.
I don’t see a problem when using IP directly. I mean the IP is static, so I could must buy a domain, but I’d also have to piss about with my setup.
I’ve emailed them. See what they come back with. I mean unless they block SSH, Wireguard and Tor, I’ve got to hand work arounds. I just doesn’t like them fighting me.
If you’re not in the UK, try a UK proxy?
O2 didn’t until recently. EE does’t currently (wife’s network)
I’ve been doing some investigating. It’s not just DNS. Termux doesn’t use the system DNS, it uses Google. But there is still a interference with SSL on 443 and a different page on port 80.
Edit: oh and the IP address is current with ping.
“This page has been blocked for either a legal or technical reason.”
But you can see the block page used yourself at: http://shieldcf.o2.co.uk/blacklist
Oh I know some ports are ok. My SSH and WireGuard get through. Port 80 is redirected to a block page place holder and 443 is interfered with so SSL fails.
I hope it continues to be a non issue for you. Without you having to take any measures. Just saying it can be an issue. Search “zigbee 2.4ghz wifi interference” if you don’t believe me.
