How the Modern Web and HTTPS Emerged from Simple Two-Computer Networks

The article traces the evolution of internet infrastructure from two friends connecting PCs with twisted-pair cable and assigning IP addresses to the global system of DNS, routing, and public-key certificates.

It explains how early local networks expanded with switches, always-on servers, and domain names to solve the problem of changing IP addresses. As networks grew and interconnected through routers and ISPs, new risks of eavesdropping and traffic redirection appeared on open paths.

The solution introduced centralized certificate authorities such as the fictional Sectigo that issue chained certificates rooted in pre-installed trust stores.

The piece details the structure of certificates, key pairs, signing chains, and the browser validation process that enables encrypted HTTPS sessions.

Written in accessible language with deliberate simplifications, the text serves as an educational overview rather than a technical manual.

Amazon Confirms Irrecoverable Data Loss in UAE and Bahrain Data Centers After Drone Attacks

Amazon Web Services has officially confirmed that data stored in specific availability zones within its Middle East regions was permanently destroyed following physical attacks on data centers in the UAE and Bahrain. The incidents began on March 1 and continued through April and July, damaging infrastructure tied to AI development projects. In the UAE region mec1, only zone mec1-az2 was completely destroyed with no external backups, while mec1-az3 suffered severe damage and mec1-az1 remained operational but overloaded. All three zones in the Bahrain region me-south-1 were rendered inoperable. AWS had spent six months attempting recovery before issuing the final statement on September 15, 2026, and has advised customers to migrate workloads to unaffected regions. The event highlights growing risks to data from physical-world attacks beyond traditional network threats.

Bots Overload OT Commerce Store on OT Box, Spike Paid OTAPI Calls Mistaken for DDoS Attack

An online store running OT Commerce experienced CPU loads reaching 98-100% and a 6-7x increase in paid OTAPI calls over three days due to automated bot traffic rather than a traditional DDoS. The site owner had already deployed a paid anti-bot module on the VPS, yet behavioral bots continued to bypass protections and force expensive calls to the external OTAPI platform for product data from Taobao, Tmall, 1688 and other marketplaces. Traffic analysis after switching to the CRONARMOR WAF revealed that 41.9% of page requests were automated, with 99.3% of early-stage automation blocked before reaching the origin server. Only 0.5% were behavioral bots visible in analytics, while legitimate search crawlers accounted for 27,190 requests that were explicitly allowed. The WAF approach stopped requests at the reverse proxy layer, preventing PHP execution, database queries and OTAPI billing events on the origin. Post-deployment CPU dropped to single digits for most of the day, eliminating both performance issues and the anomalous rise in paid API usage.

Teenage Smartphone Addiction: Causes, Consequences, and Treatment Approaches

Smartphone use has become an integral part of adolescent life, but problematic usage patterns rather than device ownership itself are the focus of concern. Medical experts avoid the term smartphone addiction and instead address issues like disrupted self-control, social media overuse, and gaming disorder that interfere with sleep, studies, relationships, and mental health. Data from Pew Research indicates nearly 50% of U.S. teens aged 13-17 are online almost constantly, while CDC findings link four or more hours of daily screen time to elevated anxiety and depression symptoms. Family digital habits strongly influence teen behavior, and rigid bans often fail without addressing underlying issues such as boredom, anxiety, or social isolation. Parents are advised to track specific disruptions over a week and consider professional help when signs of depression, bullying, or self-harm appear alongside device overuse.

VK WorkSpace Federation Enables Secure Multi-Organization On-Premise Messaging Without Infrastructure Merge

VK Tech has released federation capabilities for its VK WorkSpace corporate messenger that connect independent On-Premise installations while preserving each organization's full control over data, administration, and security policies. The feature, first piloted in November 2025 and expanded in the July 2026 26.2 release, supports multi-party chats across more than two separate environments. Federation relies on mutual trust establishment and per-user access grants rather than full directory replication or proxy access to a single host instance. Each participating organization maintains local copies of messages, files, and chat metadata, allowing continued access even if a partner installation becomes unavailable. The architecture deliberately avoids both centralized hosting and open protocols such as Matrix to keep changes to the existing messenger core minimal. Administrators retain independent levers to create or revoke trusts and to limit which employees may communicate externally.
