Two notable outages


On July 10, Hurricane Electric, a network transit provider based in Fremont, CA, experienced an outage that impacted customers and downstream partners across multiple regions, including the U.S., Mexico, Canada, Japan, Hong Kong, India, the Philippines, Singapore, Malaysia, Indonesia, Belgium, Bulgaria, Vietnam, and Thailand. The outage was first observed around 12:30 AM EDT and lasted a total of 30 minutes over a period of 50 minutes. The outage initially appeared to be centered on Hurricane Electric nodes located in Singapore, Hong Kong, and Frankfurt, Germany. Around twenty minutes into the outage, those nodes were joined by nodes located in Chicago, IL, in exhibiting outage conditions. Ten minutes after appearing to clear, nodes located in Singapore, and Frankfurt, Germany, once again began exhibiting outage conditions. The outage was cleared at around 1:30 AM EDT. 

On July 8, Unitas Global, a US-based network transit provider that merged with PacketFabric in 2023 and is now operating as PacketFabric, experienced an outage that impacted customers and downstream partners across multiple regions, including the U.S., Turkey, Canada, Singapore, the Netherlands, India, Switzerland, Germany, Malaysia, Greece, and France. The outage was first observed around 8:11 PM EDT and lasted a total of 34 minutes over a period of 54 minutes. The outage initially appeared to be centered on Unitas Global nodes located in Washington, D.C. Around six minutes into the outage, the nodes located in Washington, D.C., appeared to clear and were replaced by nodes located in New York, NY, in exhibiting outage conditions. Five minutes after appearing to clear, nodes located in New York, NY, and Washington, D.C., once again began exhibiting outage conditions. This rise in the number of nodes and locations exhibiting outage conditions appeared to coincide with an increase in the number of impacted downstream partners and customers. Around five minutes further on, the nodes located in New York, NY, and Washington, D.C., were temporarily replaced by nodes located in London, England, in exhibiting outage conditions. Five minutes later, the nodes located in London, England, were replaced by nodes located in New York, NY, in exhibiting outage conditions. The outage was cleared at around 9:05 PM EDT.

Detecting Co-Resident Attacks in 5G Clouds! Detecting co-resident attacks in 5G clouds involves identifying malicious activities where attackers share physical cloud resources with victims to steal data or disrupt services. Techniques like machine learning, behavioral analysis, and resource monitoring help detect unusual patterns, ensuring stronger security and privacy in 5G cloud environments. Detecting Co-Resident Attacks in 5G Clouds In a 5G cloud environment, many different users (including businesses and individuals) share the same physical infrastructure through virtualization technologies like Virtual Machines (VMs) and containers. Co-resident attacks occur when a malicious user manages to place their VM or container on the same physical server as a target. Once co-residency is achieved, attackers can exploit shared resources like CPU caches, memory buses, or network interfaces to gather sensitive information or launch denial-of-service (DoS) attacks. Why are Co-Resident Attack...

                        Neural Networks Neural networks are computing systems inspired by the human brain, consisting of layers of interconnected nodes (neurons). They process data by learning patterns from input, enabling tasks like image recognition, language translation, and decision-making. Neural networks power many AI applications by adjusting internal weights through training with large datasets.                                                    Structure of a Neural Network Input Layer : This is where the network receives data. Each neuron in this layer represents a feature in the dataset (e.g., pixels in an image or values in a spreadsheet). Hidden Layers : These layers sit between the input and output layers. They perform calculations and learn patterns. The more hidden layers a ne...
