I have the same experience as you. I have been working with many non-native English speakers from different countries, and Americans (and to some degree Brits) are usually the ones who can't follow what is said. This improves over time as they get used to different accents, but it seems it is easier for non-native speakers to understand foreign accents than native speakers in general.
I'm not saying I always understand 100% of what is said. When someone with an accent from a specific part of a country speaks super fast and is on a poor line with lots of street traffic in the background, it can be hard to follow. But usually I catch enough of it to be able to communicate.
> How are these clowns deploying stuff on a Friday, it is unbelievable to me
I have stopped fighting this battle at work (not Cloudflare). Despite Friday being one of the most important days of the week for our customers, people still deploy the latest commit 10 minutes before they leave in the afternoon. Going on a weekend trip home to your family? No problem, just deploy and be offline for hours while you are traveling...
The response was that my way of thinking is "old school". Modern development is "fail fast" and that CI/CD with good tests and rollback fixes everything. Being afraid of deploys is "so last decade"... The problem is that our tests don't cover everything, it may not fail fast, and not all deploys can be rolled back quickly and the person who knows what their huge commit that touches multiple files actually does is unavailable!
We have had multiple issues with late afternoon deploys, but somehow we keep doing this. Funnily enough, I have noticed a pattern. Most experienced devs stops doing this after causing a couple of major downtimes, due to the massive backlash from customers while they are scrambling to fix the bug. So gradually they learn to deploy at less busy times and monitor the logs to be able to catch potential bugs early.
The problem is that not enough has learned this lesson because they have been lucky that their bugs have not been critical, or because they are too invested in their point of view to change. It seems that some individuals learn the hard way, but the organization has not learned or is reluctant to push for a change due to office politics. I decided to keep my head low and let things play out, as I simply no longer care as long as the management don't care either.
