Interesting post which links to an on-line overview of the current latencies:
Does anybody know about similar information about other big cloud providers like Amazon and Azure?

Remember the introduction of Pokémon during summer 2016? Despite usage being far less by now ([WayBack] 80 Amazing Pokemon Go Statistics and Facts) you might still recollect the odd names the Pokémon Go characters in the Pokédex had: [WayBack] List of Pokémon – Wikipedia.
Back then I had the vague sense that some names reminded me of species, and others of companies. Both appeared to be true, for instance [WayBack] Seel looks awfully familiar to Seal. Domo has many meanings (including a Dutch dairy desert). Oh, and [WayBack] Gloom has quite a few meanings so I’m OK with being confused.
So I was amused bumping into these a while back: Pokémon names versus those of names of start-up and big-data companies:
Is it a Pokemon or a BigData tech?
You is able to tell which nonsense word is Pokémon character and which is the latest craze in #bigdata technology? You just might qualify as #bigdata expert. Much success!

The quizes also have very funny descriptions of what the companies behind the names stand (stood?) for, like “Hadoop is distributed system for counting words”.
Via many, including:
Maybe I should turn the GitHub repository in to a Google Assistant Trivia questionaire using a Google Sheet.

From [WayBack] Kubernetes’ first major security hole discovered | ZDNet in reverse order:
Fortunately, there is a fix, but some of you aren’t going to like it. You must upgrade Kubernetes. Now. Specifically, there are patched version of Kubernetes [WayBack] v1.10.11, [WayBack] v1.11.5, [WayBack] v1.12.3, and [WayBack] v1.13.0-rc.1.
…
[WayBack] Red Hat said, “The privilege escalation flaw makes it possible for any user to gain full administrator privileges on any compute node being run in a Kubernetes pod. [WayBack] This is a big deal. Not only can this actor steal sensitive data or inject malicious code, but they can also bring down production applications and services from within an organization’s firewall.”
…
And the bug, [WayBack] CVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It’s a [WayBack] CVSS 9.8 critical security hole.

In this article I compare the costs of network bandwidth transferred out of Amazon EC2, Google Cloud Platform, Microsoft Azure and Amazon Lightsail.
Bandwidth costs are one of the most ridiculously expensive components of cloud computing, and there are some serious inconsistencies in the industry, especially with Amazon.
[…]
If you move a significant amount of data you should think twice before moving to the cloud, these bandwidth prices are truly ridiculous and there’s no way they can be justified when compared to colocation facilities.

Based on [Wayback/Archive.is] How to tell if your site is served via CloudFlare | Igor’s Blog, I’ve changed the script a little bit.
I’ve tested it with one of the domains from the Cloudbleed list (a pretty OK indication the site is using cloudflare) and a the example.org site that does not:
# curl -sI https://feedly.com | grep "Server\|__cfduid\|CF-RAY"
Set-Cookie: __cfduid=d779ee6e244349cf06e2707771a9185e21492589239; expires=Thu, 19-Apr-18 08:07:19 GMT; path=/; domain=.feedly.com; HttpOnly
Server: cloudflare-nginx
CF-RAY: 351e5e9af8971497-AMS
# curl -sI https://example.org | grep "Server\|__cfduid\|CF-RAY"
Server: ECS (ewr/15BD)

One day you will do containers.
If you want to know how k8n (Kubernetes) can help you with Docker containers, then read [WayBack] The Illustrated Guide to Kubernetes – The Isoblog. and watch the video below.
Very well explained!
