What & Why

A global internet outage is a significant event, with several potential causes. These can range from technical failures to deliberate attacks. Understanding why these outages occur is the first step toward preparing for and mitigating their effects.

Potential Causes

• Cyberattacks: Malicious actors can launch Distributed Denial of Service (DDoS) attacks, ransomware, or other cyberattacks targeting critical infrastructure like DNS servers, routers, and submarine cables. These attacks can overwhelm systems, rendering them inaccessible.
• Infrastructure Failures: Physical damage to key infrastructure, such as fiber optic cables, data centers, and power grids, can cause widespread outages. Natural disasters like earthquakes, hurricanes, and floods can also damage this infrastructure.
• Software and Hardware Bugs: Errors in software or hardware can lead to system-wide failures. This includes bugs in operating systems, routing protocols, and other critical components.
• Human Error: Mistakes in network configuration, maintenance, or operation can cause outages. This can be as simple as an incorrect command entered by an administrator.
• Government Actions: Governments may shut down internet access for political reasons, during times of civil unrest, or as part of cybersecurity measures. This can affect entire regions or countries.
• Geopolitical Events: Conflicts and tensions between nations can lead to deliberate attacks on internet infrastructure or disruptions in international data flow.
• Supply Chain Issues: Disruptions in the supply chain for critical hardware, such as routers and switches, can lead to shortages and failures.

The Why: Why Global Outages Matter

The impact of a global internet outage is far-reaching and affects various aspects of modern life. Here’s a breakdown: — Marlton, NJ: Zip Codes & Everything You Need

• Prepare for disaster response: Develop plans for responding to internet outages, including coordinating communication efforts and providing assistance to affected populations.

Examples & Use Cases

While a true “global” outage is rare, regional and localized outages are more common. Examining these instances can provide valuable insights into the vulnerabilities of the internet and the importance of preparedness.

Notable Outage Events

• 2021 Facebook Outage: In October 2021, Facebook, Instagram, and WhatsApp experienced a massive outage that lasted for several hours, affecting billions of users worldwide. The outage was caused by a configuration error that took down the Domain Name System (DNS) servers that direct traffic to Facebook's services.
• 2017 DDoS Attack on Dyn: In October 2016, a massive DDoS attack targeted Dyn, a major DNS provider, disrupting access to many popular websites and services, including Twitter, Netflix, and Amazon. This attack highlighted the vulnerability of the internet to attacks on its underlying infrastructure.
• 2019 Internet Shutdown in India: The Indian government has frequently shut down internet access in certain regions to prevent the spread of misinformation and control civil unrest. These shutdowns have significantly impacted businesses, educational institutions, and social life.

Case Studies

• E-commerce Businesses: E-commerce businesses rely heavily on the internet for sales, customer service, and order fulfillment. An outage can lead to a complete loss of revenue and damage customer relationships. The development of offline sales strategies and diversified payment options are essential.
• Financial Institutions: Banks and financial institutions rely on the internet for online banking, payment processing, and access to financial markets. Outages can disrupt transactions, delay settlements, and create uncertainty. Robust backup systems and network redundancy are critical.
• Healthcare Providers: Healthcare providers use the internet for electronic health records, remote patient monitoring, and telehealth services. An outage can compromise access to patient data, hinder treatment, and affect patient safety. The implementation of offline data access and redundant systems is essential.

Best Practices & Common Mistakes

Best Practices

• Redundancy: Implement redundant systems, including multiple ISPs, backup power, and geographically diverse data centers.
• Decentralization: Distribute critical services and data across multiple locations to reduce the impact of outages.
