Basecamp is under network attack (DDoS)

Basecamp was under network attack

The attack detailed below has stopped (for the time being) and almost all network access for almost all customers have been restored. We're keeping this post and the timeline intact for posterity. Unless the attack resumes, we'll post a complete postmortem within 48 hours (so before Wednesday, March 26 at 11:00am central time).

Criminals have laid siege to our networks using what's called a distributed denial-of-service attack (DDoS) starting at 8:46 central time, March 24 2014. The goal is to make Basecamp, and the rest of our services, unavailable by flooding the network with bogus requests, so nothing legitimate can come through. This attack was launched together with a blackmail attempt that sought to have us pay to avoid this assault.

Note that this attack targets the network link between our servers and the internet. All the data is safe and sound, but nobody is able to get to it as long as the attack is being successfully executed. This is like a bunch of people

This is an extraction from Jim Weirich's "Decoupling from Rails" talk, which explained how to apply the hexagonal design pattern to make every layer of your application easily unit testable (without touching the database etc). It only seeks to extract a single method, the EmployeesController#create method, to illustrate the design damage that's …
# Original Rails controller and action
class EmployeesController < ApplicationController
def create
@employee = Employee.new(employee_params)
if @employee.save
redirect_to @employee, notice: "Employee #{@employee.name} created"
else
render :new
end
