Today’s Tech Brief examines digital trust: how old mistakes haunt our infrastructure, and how even modern “intelligent” systems stumble over the basics. If you missed yesterday’s edition, catch up here before diving in.
Post Office Horizon Fallout: Critical System Defect Ignored for Years
“We kept saying it wasn’t right, nobody listened.” That’s the chilling core from this week’s public inquiry, as a forensic investigator reveals that a major defect in the Post Office’s Horizon system festered unchecked. Hundreds of Post Office operators lived a modern nightmare, with system errors translated into criminal prosecutions. The human cost was severe: lives overturned, reputations and livelihoods destroyed. Yet the bugs were not buried deep in obscure code. Internal engineering notes and archived tech reports flagged issues, but institutional inertia won.
It matters, painfully so, because modern systems, for all their polish, are often just as brittle beneath. Trust is earned, not coded by default. Digital literacy is not nostalgia; it’s the defence we need when “official” tech goes wrong. The damage here was British, bureaucratic, and heartbreakingly avoidable.
Equinix Invests £3.9bn in British Datacentre Expansion
A cold fact for your morning: Equinix’s £3.9 billion play for Hertfordshire makes it one of the largest single-site datacentre investments in UK history. Forget the drama of old chip fabs; this is computing’s new concrete face, where global giants muscle in to secure storage and energy for the cloud. Regional tech folk, who once drove to Slough for rack space, are quietly hopeful. The location finally signals that tech capital is moving beyond the M25.
Datacentres are rarely loved in the way a BBC Micro or Acorn workstation might be, but they are now the backbone of everything from YouTube uploads to patch Tuesdays. This expansion may help distribute demand, reducing the stress on London and hinting again at Britain’s stubborn relevance in computing. When the servers stay warm and the cooling holds, the whole ecosystem breathes.
Apple’s Autocorrect Goes Rogue: Users Fume as AI “Improvements” Miss the Mark
Come for the “winter,” stay for the “w Inter.” Millions of iPhone users now face AI-powered autocorrect mayhem, with common words transformed into bizarre alternatives. Apple’s updated AI engine was pitched as the next leap, but experienced texters are less than thrilled. It’s not just an inconvenience; it’s a complete failure of classic usability, one that brings new respect for those crusty T9 days. Yes, even the best “intelligent” code can regress when it leaves behind the fundamentals.
If you put up with predictive text from the Nokia era, this feels like a needless retread. Simpler, rule-based systems were clunky but consistent. The problem here is not just technical; it’s cultural: modern platforms sometimes “improve” away the reliability we quietly depended on.

On This Day: 1988, Morris Worm hits ARPANET. A grad student’s curiosity unleashed havoc as the Morris Worm struck thousands of computers, exploiting vulnerabilities in sendmail and UNIX finger. This led to the invention of the first Computer Emergency Response Team, putting cybersecurity front and centre. Most sysadmins didn’t see it coming. Their scramble to patch the chaos laid the groundwork for every virus fix, hack, and emergency protocol since.
Today’s Big Question
Does digital progress mean we are safer, or have the same core flaws just changed address? Tech Brief 2 November 2025 asks if we have really learned to spot the bugs before another crisis makes the morning news. If you’ve had your own “system gone wrong” moment, reply and share it with us; your story might help someone else spot the next bug.
Stay curious, solder on, and never trust a system just because it’s “official.”
