BGP Role model: tracking the adoption of RFC 9234
RFC 9234 lets routers reject route leaks on their own, using BGP Roles and the Only to Customer attribute. We measured who has deployed it, and found two Tier 1 networks unexpectedly stripping OTC.
Fragments: August 18
Part of the reason why I’m at Thoughtworks is because I’d like to see a software development organization founded on technical excellence as an example for the rest of the industry. The trouble is that I have little aptitude or inclination for the hard work of building such an organization. So I rel...
Cloud Native platform sovereignty through multi-plane architecture
When people talk about cloud sovereignty, the conversation often starts with regions: where a workload runs and where its data is stored. But choosing a region is only part of the story. The architecture of the...
Consistency is the new latency: AI at the data layer
As AI agents move from chatbots to taking action, their reliability depends on the consistency of the data layer beneath them. This post examines how replication lag poisons an agent's context and shows how to match Amazon Aurora, Amazon DynamoDB, and Amazon Keyspaces replication models to each task...

From OpenTofu to Argo CD: GitLab as your AWS control plane
Configuring cloud-based environments is complex, as it requires considering networking, subscriptions, services, and all the components that make up the underlying infrastructure. Manual setup is error-prone, inconsistent, and difficult to reproduce. This tutorial shows how to set up a fully automat...
Avoid the massive end-to-end tax of default full history clones
It's easy to think of git clone as a client-side operation, but the settings of this operation impact the server side and all networks in between. When you run a default full history clone, the server has to walk the entire history, build a pack file for it (that's what "counting objects" is actuall...
