How GoDaddy Brought Down Millions of Sites – and How to Avoid Being a DNS Out...Yottaa
- GoDaddy experienced a 6-hour outage in September 2012 that brought down 45 million websites registered through GoDaddy. This was caused by internal network events that corrupted router data tables, not by an external attack.
- DNS (Domain Name System) is crucial infrastructure that translates human-readable domain names to IP addresses, allowing websites and email to function. GoDaddy hosts DNS for domains registered through them.
- When choosing a DNS service, factors like reliability, performance, security, and geographic distribution should be considered to avoid a single point of failure bringing all sites down.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
