On October 4th, Facebook, Instagram, and WhatsApp experienced a significant outage that lasted for several hours. This event highlighted the interconnectedness of the internet and its potential vulnerabilities. During this time, Cloudflare's public DNS resolver, 1.1.1.1, saw a massive spike in SERVFAIL codes due to its inability to access Facebook's authoritative servers. The incident also led to increased traffic for other sites as users sought alternative platforms for communication and entertainment. Additionally, websites that relied on Facebook scripts experienced slower page load times during the outage. Overall, this event served as a reminder of the importance of resilience and collaboration within the internet industry.
