#2I'm a fan of the show, it was really entertaining to listen to knocking the site over "live".
Re: New setup for 2020
#3Is this really “simpler” as they claim? It reads a bit like the honeymoon phase and I’m a lot more interested in how they feel about the new stack 1 or 2 years down the line.

#4I was baffled by this:
"The worst part is that serving the same files from disks local to the VMs is 44x faster than from persistent volumes (267MB/s vs 6MB/s)."
Is it a configuration issue on their side or do the LKE volumes are really limited to 6MB/s on linode?
How can you be happy with this for production??

#5It seemed interesting and I tried to subscribe but the process doesn't work without disabling ublock/adblock. I am okay with that so I disabled it but then I failed two captchas round (find bikes in thumbnails, some thumbnails are upside down ?!) :(.

Block storage is an area that we are working with Linode to improve. That's the random read/write performance, as measured by fio.
We have mostly sequential reads & writes (mp3 files) that peak at 50MB/s, then rely on CDN caching (Fastly makes us happy in this respect).
CDN caching is something that we are currently improving, which will make things quicker and more reliable.
The focus is on reality vs the ideal, and the path that we are taking to improving not just changelog.com, but also our sponsors' products. No managed K8S or IaaS is perfect, but we enjoy the Linode partnership & collaboration ;)

That was my favourite part too!
Yes, we could have mitigated that entirely with CDN stale caching, but it was good to see what happens today, and then iterate towards better Fastly integration.

Hey, that speed was good enough in ~1995!

Sorry for the hassle! We’ve been hit by lots of spammers lately so I battened down the hatches. Unfortunately this has the side effect of also blocking some legit humans as well. :(

#10Isn't changelog.com mostly a static site? What kind of workloads do they run/monitor/update with all this infrastructure?
