youtube.com not resolving

This started yesterday but until then youtube had been working fine.
Now on two different PCs, I am unable to visit youtube.com.
I have tried using my local custom written dns server / resolver, plusnet HubOne and finally Google's own 8.8.4.4 dns server
As you can see every dns server used reports the same IP address - 172.217.169.78. Somehow I don't think Googles dns server.is wrong about it's own IP address for youtube.
Would somebody at plusnet please explain what is going on?

@7up as was said this really doesn't help you but I can get to youtube.com so to me this means that it's
A. A fault on your side
B. A local issue
C. A routing issue.
What do you get with a traceroute to the IP?
Also I get this using nslookup.

Name: youtube.com
Address: 172.217.20.142
Name: youtube.com

You could edit your hosts file and set this IP to resolve to youtube.com to see if it works. If it does then there may be an issue with the server at the address you provided.

Well i've concluded it's not a fault at my end - not if googles own dns server at 8.8.4.4 is providing the same IP...
So I opened up another chrome window - and CTRL+Click'ed the youtube icon on my bookmarks bar repeatedly... opened up several hundred tabs... eventually chromes cache timed out and looked it up again finding 216.58.213.14 which works (I later found a way to clear chromes cache the easy way lol).
Anyway as that IP seems to work i've added it into my external domains zone on my dns server for both youtube.com and www.youtube.com.
It's a dirty hack and leaves me vulnerable to not having the latest IP if they change it but for now it's working.

For what it's worth I get this for youtube.com:
nslookup youtube.com 8.8.4.4

Name: youtube.com
Address: 172.217.169.46

and for www.youtube.com I get:
nslookup www.youtube.com 8.8.4.4
Server: 8.8.4.4
Address: 8.8.4.4#53

Nothing, that I'm aware of
I resolve to the same IP and can access the site successfully.

Well there must be something going on Bob, i couldn't get 3 devices to work using that IP - my phone refused to connect too. The moment i rigged the DNS to that other IP everything could connect to youtube.
This isn't a local fault at my end.. i suppose google might have blocked an ip range on that server for whatever reason but that seems unlikely.
