- Oct 9, 2026 Abort Paths and the Blackout Window A migration can fail at any point, and what the guest experiences depends on which side still holds a complete state. The ordering of commit, acknowledgement, and source teardown defines what rollback is possible. virtualization
- Aug 21, 2026 Rollback as a Question of Write Reversibility Why reverting traffic is easy and reverting state is not, how dual-write and tombstones change the rollback budget, and when a cutover becomes one-way. cloud infrastructure
- Jul 24, 2026 Model Registries and Promotion Gates Between Training and Traffic What a registry records about an artifact, how staging transitions are gated on evidence, and why the serving path must resolve versions rather than names. machine learning
- May 1, 2026 Reversibility as the Currency of Architectural Decisions Decisions differ less in how good they are than in what it costs to undo them. How to classify one-way doors, what preserving an option costs, and how to test a rollback path. software architecture
- Mar 26, 2026 Rollback Boundaries: Which Layers a Reversal Can Restore Code, configuration, schema, data, messages, and external effects each reverse differently; how to place the irreversible step last and keep a rollback window that is real. devops
- Mar 9, 2026 Rolling Back a Stateful Serving Fleet Under Live Traffic Restoring an earlier model is simple until the serving fleet holds request state, warm caches, and in-flight streams; then the rollback itself becomes a state transition with its own failure modes. inference systems
- Feb 1, 2026 Switching the Write Path: Cutover, Rollback, and the Point of No Return How to move writes to a replacement store without a window of two writers, what rollback actually requires after new-only data exists, and how to decide when reversal stops being possible. software architecture
- Dec 16, 2025 Automatic Rollback Controllers and the Ways They Misfire A controller that reverts a deployment on a metric threshold is a feedback loop wrapped around a feedback loop; its failure modes are oscillation, latency in the evidence, and disagreement about what baseline means. inference systems
- Dec 11, 2025 Rollback Union-Find and Offline Dynamic Connectivity How to undo a union by recording only the parent slot it overwrote, and how a segment tree over time turns edge insertions and deletions into a stack of reversible merges. data structures
- Sep 23, 2025 Shipping Shared Code Outside the Release Cycle Delivering the shared layer as a replaceable bundle decouples it from the native shell, which turns every release into a matrix of shell and bundle versions and every rollback into a data-compatibility problem. mobile computing
- Jun 19, 2025 Rolling Back a Change That Already Mutated State Why reverting a binary does not revert its writes, which mutations admit a compensating action, and how to decide before deployment whether a rollback path exists at all. distributed systems
- Mar 28, 2025 Rollback Without Downgrade: Containment After a Bad Release Ships Why the installer cannot un-ship a build, how remote configuration and feature gating contain a defect, and which failures those mechanisms cannot reach at all. mobile computing
- May 1, 2023 Confirmed Commit and Automatic Rollback for Remote Configuration Changes How a candidate datastore plus a confirm timer bounds the damage from a configuration change that severs the connection used to make it, and where the mechanism fails. networking
- Dec 13, 2021 Trial Boot, Confirmation, and Automatic Rollback How a new image is allowed to run under supervision, what counts as proof that it works, and why the confirmation step has to come from the application rather than the bootloader. embedded systems
