In case you didn’t read about it elsewhere

Websites hit by global outage https://www.bbc.co.uk/news/technology-57929544

Dunno. Did anyone actually notice?? 😂

Far less sensational and pretty boring if they bothered explaining, at least briefly, that one of the key design goals (and baked in over the last 30 to 40 years of existence) of the internet and it’s various protocols and routing (fundamentally TCP/IP, store and forward and packet switching) was rooted in the Cold War and DARPA requirements that it was able to continue to function with large chunks broken or compromised, “survivability”

Until many websites rely on these CDN companies products. One CDN goes down and hundreds of websites that reference it don’t work. You can still ping the servers but the web applications fail.

Not sure the web app and CDN designers understood the resilience model.

Eggs in one basket 🧺 and all that. How many CDN fails will it take…

agreed, I wonder how many ISPs DNS referred up to Akamai's DNS service.

Cascade failure?

Oh, well I didn't even notice a thing, and I was online throughout Wednesday to today, but I use several DNS Servers for IPv4 and IPv6 so if one failed it would use the next and I was even on steam all day Thursday and it was fine for me.

This was over 2 weeks ago.

Your use of multiple DNS servers wouldn't have helped though.
It was Akamai's DNS that broke, meaning nobody could access the affected sites regardless of their own DNS settings.

Oh man, I must remember to look at the date stamp LOL

True.

I didn't notice issues with websites back then, that I recall. However, my local network goes through something called Technitium - which does recursive resolution instead of me using public forwarders like Google's 8.8.8.8/8.8.4.4 DNS. Could that have made any difference for me or was I just simply lucky that I may not have accessed any affected websites or had such DNS records already cached temporarily?

It wouldn't have made a difference because it would need to recurse all of the way back to Akamai anyway e.g your resolution would look something like this:

* Query the root name servers for the .com zone
* Query the .com nameserver for example.com
* Get back a CNAME pointing to Akamai
* Query Akamai for the address of that CNAME
* Some random error occurs here because their DNS is down

You were either lucky or had the affected domains cached just long enough that you didn't notice.
