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

Amazon Web Services has confirmed the permanent loss of customer data following physical attacks on its data centers in the United Arab Emirates and Bahrain. The incidents, attributed to Iranian drone strikes, began on March 1 and extended into April and July, affecting facilities involved in artificial intelligence projects.

After six months of recovery efforts, AWS issued an official statement on September 15, 2026, acknowledging that data in certain availability zones could not be restored. The company had previously released only interim technical reports without confirming total loss.

Impact on UAE Region mec1

The UAE region consists of three zones: mec1-az1, mec1-az2, and mec1-az3. According to the AWS Health Dashboard:

  • mec1-az1 sustained no physical damage and operates normally, though it faces overload issues.
  • mec1-az2 was completely destroyed with no possibility of data recovery, as it lacked backups outside the zone. All customer data stored exclusively on disks in this zone is irretrievably lost.
  • mec1-az3 suffered serious damage, but engineers continue attempts to recover infrastructure and surviving data.

The affected UAE project, linked to an OpenAI lease, had its contract suspended following the attacks.

Bahrain Region me-south-1 Status

In Bahrain, the situation proved more severe. All three zones — mes1-az1, mes1-az2, and mes1-az3 — that form the me-south-1 region were completely taken offline with no recovery options reported.

AWS has recommended that customers relocate workloads to other unaffected regions to mitigate further risks.

Yandex Disk Files Become Partially Inaccessible After Sasovo Data Center Incident

A detailed user report reveals that approximately one percent of files stored on Yandex Disk are currently unavailable for download following reported incidents at the Sasovo data center. The problems manifest in three distinct states: missing thumbnails with downloadable originals, visible thumbnails with inaccessible originals returning 504 Gateway Time-out errors, and cases where both thumbnails and originals fail to load. Technical analysis using curl requests traced the failures to specific storage nodes such as s418klg.storage.yandex.net, indicating that some data shards may reside in affected infrastructure while others remain operational. Yandex support requested original files for diagnosis but closed the ticket without providing an official explanation or confirming data integrity. The author emphasizes that the issue affects files across both the Photos and Files sections and recommends maintaining offline backups due to the lack of guaranteed availability during data center failures.

Keurig K-Supreme Smart Coffee Maker Generates Nearly 1 TB of Outbound Traffic in Ten Days

A Keurig K-Supreme Smart coffee maker unexpectedly produced around 1008 GB of outgoing traffic over ten days, overwhelming a home UniFi access point while generating only 9.94 GB of inbound data. The device had been placed on a separate network segment, yet the traffic remained largely internal to the home LAN rather than traversing the internet connection. The anomaly was discovered by user Nomad while assisting family members with network maintenance through the UniFi dashboard. After the coffee maker was powered off, the issue could not be reproduced in subsequent testing, and no packet captures were available to determine the content or root cause of the traffic. The model requires internet connectivity for remote control, scheduling, capsule recognition, and automatic reordering of coffee supplies. No similar incidents have been reported by other users, and the manufacturer has not issued any statement regarding the event.

Hash Functions Part 1: Core Properties, Security Requirements and Practical Applications

The article provides a detailed introduction to hash functions, explaining how they map arbitrary-length input to fixed-length output while satisfying three fundamental security properties. It covers preimage resistance, second preimage resistance, and collision resistance, along with the avalanche effect that makes even minor input changes produce unrecognizable output. The text explains why a 256-bit digest is required to achieve 128-bit collision resistance, referencing the birthday paradox and its implications for MD5 and SHA-1. Practical guidance includes using OpenSSL for hashing, applying hashes in commitment schemes, enforcing subresource integrity on web pages, and securely storing passwords with Argon2 and bcrypt. The post emphasizes that hash functions alone do not guarantee integrity without proper transmission of the digest and announces a follow-up on SHA-2 and SHA-3 internals.

Digital Twins Enable Pre-Deployment Testing and Post-Change Control in Complex Multi-Vendor Networks

UserGate and Hadal Project experts presented a joint approach at Saint HighLoad++ that combines physical labs, emulation, and simulation into a single lifecycle for validating network changes. The method addresses recurring failures such as IPsec tunnel outages after routine software updates that pass vendor checks yet break branch connectivity. Three complexity sources—multi-vendor environments, historical configuration debt, and continuous dynamic updates—are mitigated by maintaining an always-current network model. Physical laboratories provide hardware-level accuracy for critical devices, while uInfraTwin emulation allows rapid, repeatable testing of configuration scenarios with traffic generators. Simulation tools including Batfish, Hadal, Forward Networks, and IP Fabric deliver end-to-end reachability analysis across tens of thousands of nodes without sending test traffic on production networks. The integrated digital twin continuously updates from live infrastructure, feeds selected segments into safe test environments, and verifies policy compliance after deployment.
