I’m a fan of single-AZ architecture for things that can be down once in a while; AWS is generally excellent.
I would not consider “a financial trading platform” to be one of those things.

Unfortunate optics for Coinbase to have an hours-long outage when customers could not trade, a few days after their CEO said how non-technical teams are shipping code to production. This outage is because Coinbase seems to have a hard dependency on AWS, and when AWS (or a part of it) is down, so is Coinbase This is a choice/tradeoff by Coinbase’s eng team.

What's a scientific discovery that sounds completely fake but is 100% real and still blows your mind?

@KrisSchnee @carterhambley So $2 from a reasonable source, right?

@carterhambley U-Line is selling the weighted, reflective kind for $21-37. So good guess.

@brian_armstrong Not relevant:
“The root cause was a room overheating in an AWS datacenter when multiple chillers failed.”

We experienced an outage at Coinbase last night, which is never acceptable. The root cause was a room overheating in an AWS datacenter when multiple chillers failed. We design our services to be redundant to downtime in any one AWS Availability Zone (AZ), and most of our systems worked this way last night, but not all.
Our centralized exchange did not. Exchanges have unique architectures that optimize for latency and co-location of clients. It is possible to make exchanges resistant to AZ failures, but this can introduce latency delays that are not desirable along with breaking customer co-location. Given this incident, we'll revisit these tradeoffs to ensure we're giving you the best possible venue to trade. At a minimum, the duration of an outage should be able to be reduced considerably when an AZ move is needed.
Thank you to the AWS and Coinbase teams for working through the night to mitigate the issue. We’ll share the detailed technical summary once it's ready.

Gordon Ramsay on what it really takes to run a successful restaurant:
That $25 cheeseburger isn’t a rip-off. It’s a thick, high-quality patty (chuck + short rib blend), a proper brioche bun, and premium toppings.
But the real killers behind high prices? Brutal rent and labor costs. Landlords raise the rent when you succeed… and still demand it when you struggle.
Ramsay’s best tell for a truly great restaurant:
It’s packed on a Monday night. Weekends fill themselves. Surviving (and thriving) on slow nights is what separates the winners.
Restaurant prices look insane until you see the brutal economics of keeping the doors open every single day.
I’ve always liked Ramsay’s no-nonsense style, and this is a perfect example — a busy restaurant on a quiet weekday is often one of the best signs of real quality.
What do you think — is a packed Monday night the ultimate test of a good restaurant, or do you have a better tell?

@AlexH_Johnson Some transactions may have costs, of course. But what are the odds that the natural cost happens to be what's charged by a 70 year old monopoly?
