The Saga Is Antipattern<\/a><\/div>\n
\n

In case you weren\u2019t familiar with the Saga pattern like I was, it\u2019s basically a pseudo-transaction across multiple microservices<\/a>. Here\u2019s why it might not be a great idea.<\/p>\n

\n
The Story Behind Last Week\u2019s Let\u2019s Encrypt Downtime<\/a><\/div>\n
\n

During a rolling deploy, for a very brief period of time, different parts of the infrastructure had old or new code running, with unexpected results.<\/p>\n

Generating sequential numbers in a distributed manner<\/a><\/div>\n
\n

On its face, we have a simple requirement:<\/p>\n

Generate sequential numbers
\nEnsure that there can be no gaps
\nDo that in a distributed manner<\/p>\n

It\u2019s never simple with distributed systems.<\/p>\n<\/div>\n<\/div>\n

Lost in transit: debugging dropped packets from negative header lengths<\/a><\/div>\n
\n

In classic Cloudflare style, here\u2019s an ultra-deep dive into the kernel to find the source of trouble-making packet loss.<\/p>\n

\n
There Are No Repeat Incidents<\/a><\/div>\n
\n

Even with a \u201cduplicate\u201d incident, there\u2019s always at least one thing that\u2019s different: the fact that it\u2019s happened before. That changes things. In practice, a lot more will be different too.<\/p>\n

Why So Many Companies Run in AWS us-east-1<\/a><\/div>\n
\n

There are definitely pros and cons to being in the most popular (and most oft-maligned) AWS region.<\/p>\n

What Is That Change Which Is The Source Of All Instability?<\/a><\/div>\n
\n

Changes are frequent causes of incidents, but what exactly counts as a change? This article delves into that with examples.<\/p>\n

Collision with the Terminal: The crash of RwandAir flight 205<\/a><\/div>\n
\n

This crash is a great reminder that we have to look past \u201chuman error\u201d to the systems around the humans that set them up for failure (or don\u2019t set them up for success).<\/p>\n
