October 2025 is still tough in cloud computing, as Amazon Web Services and Microsoft Azure two major cloud providers experience a massive outage, affecting a multimillion userbase, and who knows how many systems worldwide. Not only do these massive outages expose the fickle and brittle nature of the increasingly well-connected global cloud infrastructures, they also reiterate the cloud’s complexity and demand for solid development and infrastructure oversight. In this article, we break down both outage incidents including the timing, the technical cause of the incidents, overview of the service impact, and much-needed lessons for cloud architects and DevOps dots.

Logs to Unclog: The Complete Guide to Logging
Introduction to Logging
What Are Logs?
Logs are chronological records of events that occur within software applications, operating systems, and network devices. They serve as the digital equivalent of a ship’s logbook, documenting what happened, when it happened, and often providing context about why it happened.
Why Logging Matters
In today’s distributed systems and microservices architectures, logging is not just helpful — it’s essential. Here’s why:
- Debugging: Logs provide crucial information for identifying and fixing bugs
- Monitoring: They enable real-time monitoring of system health and performance
- Security: Logs help detect security incidents and unauthorized access
- Compliance: Many regulations require comprehensive logging for audit trails
- Performance Analysis: They help identify bottlenecks and optimization opportunities
- Business Intelligence: Application logs can provide insights into user behavior and business metrics

The $23 Million DNS Disaster: Why CoreDNS is the Internet’s New Superhero
The DNS Revolution That’s Changing Everything
Last December, a single DNS misconfiguration at a major streaming platform caused a global outage that cost $23 million in lost revenue and affected 180 million users during the World Cup final. The root cause? Their legacy DNS server couldn’t handle the traffic spike, taking 47 minutes to resolve the issue.
Meanwhile, their competitor running CoreDNS experienced the same traffic surge but stayed online, gaining 2.3 million new subscribers that day.
This isn’t just another “infrastructure matters” story. This is about the invisible foundation of the internet that separates digital empires from digital disasters.

How One PostgreSQL Version Mismatch Cost a Fortune 500 Company $4.7 Million
TL; DR — When Simple Becomes Catastrophic
Last month, two digits in a database version number brought at a Fortune 500 company a production outage that cost $4.7 million in lost revenue. The root cause? Their staging environment was running on PostgreSQL 13 while production was on PostgreSQL 15. A simple version mismatch became a career-ending incident.
This isn’t just another “environments matter” story. This is about the invisible architecture of trust that separates unicorn startups from digital graveyards.
