The previous bucket had intelligently adapted its partitioning to our specific traffic pattern. The new bucket had zero history and its default partitioning was a terrible fit for our workload. Fun fact: when an S3 server is overloaded it will return a 503 Slow Down

Straight from the AWS docs: “Your application can achieve at least 3,500 PUT/COPY/POST/DELETE or 5,500 GET/HEAD requests per second per partitioned Amazon S3 prefix”. We shard our data across extremely granular S3 prefixes, so it’s impossible for us to hit these limits. Confused by this apparent contradiction we investigated deeper.

we had an incident because we migrated traffic to a brand new s3 bucket. our millions of servers instantly crushed the new bucket’s partitions and started getting slammed with 5xx errors

Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.
