Lock Prediction for Zero-Downtime Database Encryption
Modern enterprise database systems face significant challenges in balancing data security and performance. Ensuring robust encryption for sensitive information is critical for systems' compliance with security standards. Although holistic database encryption provides strong protection, existing database systems often require a complete backup and restore cycle, resulting in prolonged downtime and increased storage usage. This makes it difficult to implement online encryption techniques in high-…

Ich habe einige Sachen die ich gerne immer in Sync halte (Kalender #DevonThink einige aktuelle Projektdaten) nach der unscheduled downtime der #OvGU Cloud Anfang letzter Woche schon auf mein privates NAS verlegt. Eigentlich denke ich, das hat keine USV, ist nur mit DSL angebunden und wird von einem Amateuer gehostet, aber ehrlich gesagt ist es deutlich hochverfügbarer als die #OvGU Cloud, die von ihrer scheduled Downtime am Freitag Samstag immer noch nicht wieder da ist.

Corollary: if you don’t schedule downtime for your introverted employees, Workers’ Compensation will schedule it for you. https://beige.party/@trickykat/115109100727856976

(of course one should account for the 5 seconds of downtime they have almost every single night when stuff reboots or upgrades. It's not great.)

In PostgreSQL, managing schema changes without experiencing downtime can be quite challenging. At this year’s Berlin Buzzwords, Gülçin Yıldırım Jelínek explored locking mechanisms in PostgreSQL, specifically focusing on table-level locks acquired through Data Definition Language (DDL) operations, and discussed various tools and techniques that can help minimise the impact of locking.

Perhaps it’s time to return to DNS’s original distributed design.

Cloudflare 1.1.1.1 Incident on July 14, 2025
On July 14th, 2025, Cloudflare made a change to our service topologies that caused an outage for 1.1.1.1 on the edge, resulting in downtime for 62 minutes for customers using the 1.1.1.1 public DNS Resolver as well as intermittent degradation of service for Gateway DNS. We’re deeply sorry for this outage. This outage was the result of an internal configuration error and not the result of an attack or a BGP hijack. In this blog post, we’re going to talk about what the failure was, why it o…

Innovative Distributed Maintenance Concept: From the design to cost optimisation
This study proposes an integrated heuristic framework for the strategic optimization of distributed maintenance operations in geo-distributed production systems (GDPS). It introduces a dual-entity maintenance structure comprising a Centralized Maintenance Workshop (CMW) and a Mobile Maintenance Workshop (MMW), aimed at minimizing total long-term maintenance costs. The cost function incorporates transport, operations, and downtime penalties, optimized via a two-stage algorithmic approach: a Main…

Apologies for the downtime on phpc.social this morning. Restarted services a little too early. We're good to go now (indexing ElasticSearch items in the background for the rest of the day but the site is functional otherwise).
In related news, phpc.social is now running Mastodon 4.4.1, hence it looking a bit different from before if you're using the web UI.

Today, we visited our lawyer to sign the documents for our sale of our current home (official closing June 20th) and for the purchase of our next house (close date June 23rd). Then, I came home and cut a half acre of lawn for the final time.
Approximately 42 hours until the movers arrive on the 19th , then they deliver on the 24th. The 4 days in between will be spent in my brother's bunkie at his cottage near our new house. So we have a bit of downtime to nap or explore.

Multipathing: it makes fixing cabling issues so much easier. Swapped out the 2x2m fiber patches to the NAS with 2x5m ones because the old ones were just a smidge strained. Had absolutely no issues swapping them out one by one and no downtime.

Reading through the changelog, I’m struck by how many new features we have. How is it platforms like Threads, Bluesky, and Twatter take forever to release a new feature with the huge resources they have???

Dynamic Software Updating in Java - Comparing Concepts and Resource Demands
Dynamic software updating (DSU) is an extremely useful feature to be used during the software evolution. It can be used to reduce downtime costs, for security enhancements, profiling and testing the new functionalities. There are many researches and solutions on dynamic software updating regarding diverse problems introduced by the topic, but there is a lack of research which compare various approaches concerning supported changes and demands on re-sources. In this paper we are comparing curren…

On Fault Tolerance of Data Storage Systems: A Holistic Perspective
Data storage systems serve as the foundation of digital society. The enormous data generated by people on a daily basis make the fault tolerance of data storage systems increasingly important. Unfortunately, modern storage systems consist of complicated hardware and software layers interacting with each other, which may contain latent bugs that elude extensive testing and lead to data corruption, system downtime, or even unrecoverable data loss in practice. In this chapter, we take a holistic v…
