Since posting and suggestions here I've become convinced it's the DNS cache at my service provider and that they're ignoring other DNS requests. It's all going through their modem/router where I don't have admin privileges.
I did read that most SOHO level routers have their own DNS server acting as a cache. Presumably they can't decrypt VPN traffic, but they can hijack/ignore DNS requests. Or the router cache is overly aggressive perhaps?
I'll give it another day or two and if it doesn't self-correct I'll contact them.
Weird that it's a single site (that I've discovered so far) and co-incident with DDG's new SSL certificate.

Given that the traceroute I ran listed 9 hops I think it's the ISP's server that's cached the wrong value.

I agree.

Interestingly using dig with my ISP's DNS servers gives the same IP address as I get with the google and cloudflare servers.
Since only the VPN has worked I guess they are ignoring other DNS requests and it's somehow wrongly using a google address.

See my reply to password1 for more strange behaviour.
Similarly using the IP address you posted directly in my browser (https://52.142.124.215 ) presents as duckduckgo.com in the address bar but displays the google 404 page???

Note that it is oddly different from the one posted by @ProtectedI visit https://20.43.161.105 in my browser and I get an SSL warning:
Warning: Potential Security Risk Ahead - I usually see these when a website forgets to renew their SSL certificate. Clicking on the Advanced button then displays:
Websites prove their identity via certificates. irefox does not trust this site because it uses a certificate that is not valid for 20.43.161.105. The certificate is only valid for the following names: *.duckduckgo.com, duckduckgo.com Error code: SSL_ERROR_BAD_CERT_DOMAINWeird.
When I view the certificate it looks like a valid certificate for DDG issued by DigiCert Inc.Interestingly is says:

After clicking THAT links I then see google 404 not found page again!

Solution
I added 20.43.161.105 duckduckgo.com to my hosts file and everything is working fine now.
I also changed DNS servers away from my ISPs, thanks to all the recommendations in this thread.cat /etc/resolve.conf nameserver 1.1.1.1 nameserver 1.0.0.1That seems to be working

traceroute to duckduckgo.com (202.39.62.156), 30 hops max, 60 byte packets 1 * * * 2 * * * 3 * * * ... 30 * * * *Why do ping and traceroute not use the new DNS server's I've configured (after re-booting too_)
The only thing to work is to add20.43.161.105 duckduckgo.comto my hosts file and now everything seems to be working as expected, though I have doubts now that changing the DNS configuration has done any good.
I know ISPs cache things like youtube to reduce costs so I'm wondering if 202.39.62.156 handled caching of duckduckgo, and they pointed their nameservers there and that box is broken.
Thanks for everyone's input and patience (lol are you still reading???)
Original Question
I've used Duck Duck Go as my main search engine for many, many years.
I have several search engines installed in Firefox including 2 for duck duck go. One for the /lite version and one for the full version.[See update at bottom]
In recent days neither of these work. I would type my query into the search engine, press enter as I have done for years.
All I see is a blank page.
The latest development is that when I try and enter ANY search to either of those engines I get a GOOGLE 404 not found page.
traceroute duckduckgo.com ─╯ traceroute to duckduckgo.com (216.239.38.120), 30 hops max, 60 byte packets 1 * * * 2 * * * 3 The usual internal routing of my ISP 4 "" "" "" 5 "" "" "" 6 "" "" "" 7 "" "" "" 8 * * * 9 any-in-2678.1e100.net (216.239.38.120) 4.089 ms 4.077 ms 4.181 ms ping duckduckgo.com ─╯ PING duckduckgo.com (2001:4860:4802:32::78) 56 data bytes 64 bytes from any-in-2001-4860-4802-32--78.1e100.net (2001:4860:4802:32::78): icmp_seq=1 ttl=117 time=10.1 ms 64 bytes from any-in-2001-4860-4802-32--78.1e100.net (2001:4860:4802:32::78): icmp_seq=2 ttl=117 time=8.52 ms 64 bytes from any-in-2001-4860-4802-32--78.1e100.net (2001:4860:4802:32::78): icmp_seq=3 ttl=117 time=6.87 ms 64 bytes from any-in-2001-4860-4802-32--78.1e100.net (2001:4860:4802:32::78): icmp_seq=4 ttl=117 time=8.83 ms --- duckduckgo.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3005ms rtt min/avg/max/mdev = 6.873/8.584/10.118/1.155 ms cat /etc/resolv.conf > MY ISPs name servers > MY ISPs name serversSure enough I cannot find any pages on the site 2001-4860-4802-32--78.1e100.net which is obviously belongs to google.
This is very very strange.
Could someone verify if they can use DDG or whether they see the same as me?
Does anyone have any idea what's happening?
UPDATE
I can connect to and use DuckDuckGo using a browser VPN. This appears to be a mess made by my ISP.
I'd still like suggestion to overcome the problem though.14 votes -

Comment on Great examples of explaining an algorithm (or even just a process) in ~engineering

If you have the co-ordinates of points or places, how do you find the closest pair? You could just find the distance between each pair of points and remember the closest and if you had say 10 places that would be fine. You would compare 45 distances.
Point 1 to each of 2..10 = 9 Point 2 to each of 3..10 = 8 - ignore 1 since 1 -> 2 was already done Point 3 to each of 4..10 = 7 ...I'm sure you see the pattern. What if you want to compare over 19,495 places like the cities, towns and villages in the U.S? That would be slightly over a whopping 190,000,00 comparisons.
These lectures show (and prove) how you can calculate that with about 200,000 comparisons.

A few surprises in this thread ... for example are Scorcese and Kubrick under-represented?
A toss up between Mulholland Drive and Tarkovsky's Stalker (which is his only film I've seen but left a big, big impression). I feel that Genius is thrown about for a lot of good or even great (but not actual genius) directors. I do feel Lynch deserves it though.
By the way you've done a bang up job responding to a very busy thread, cheers.

I used to rate movies on Movie Lens because I liked their recommendations at the time. I just chosen 10 of my 5.0-rated films. Problem is I stopped using it ages ago so these are historical faves. Honestly this is a fool's errand, lol. Made even worse by reading through other people's lists :(

SalviaSteroids (Anabolic)Synthetic Cannabinoids (K2/Spice)Synthetic Cathinones (Bath Salts/Flakka)- Tobacco/Nicotine and Vaping
I'm pretty sure I would have tried the rest if I'd had access to them, except Steroids.
I'm not sure if I was addicted to the harder drugs - though probably weed and alcohol. Despite the horror stories and danger, a lot of people take harder drugs recreationally, probably way more than you think - though I'm not condoning it.
I ended up in a bad way at one point. I still don't understand why but weirdly I convinced myself to spend a year in a Zen monastery in Japan. Japan is notoriously expensive so I travelled and worked (mostly illegally) through Asia trying desperately to save enough. Despite continuing my bad habits I was introduced to a yoga/meditation teacher which eventually led me to quit everything though it was quite a long struggle.
I never made it to Japan へ‿(ツ)‿ㄏ

The doctor strangles his wife after planning a trip together and she dies later in the hospital. Columbo discovers the plan to disguise his mistress/patient as his wife boarding and leaving the plane . She crumbles under Columbo's threats and pressure and agrees to fake her death at the pool (implying Columbo set this up off-screen). Overhearing the doctor's contempt causes her to fully co-operate with the police. -
