A breakdown of impact by country based on NetBlocks global metrics shows the countries most affected: Global Facebook, Instagram, WhatsApp and Messenger reachability continued to fall with 80% unable by 12:30 PM UTC Sunday 14 April. Data collected by the NetBlocks internet observatory covering the performance and availability the platforms’ CDN, backend and frontend servers during that incident pointed toward a possible issue in backend or database systems within Facebook’s own internal network, which all four services rely on:Īnalysis of 100,000 worldwide network measurements across 21 Facebook, WhatsApp, Instagram and Messenger backend/frontend servers shows no evidence of a network layer fault nor signs of a DDoS attack #FacebookDown ⬇️ /gdGM0s8x圎 The same services were previously disrupted in a similar fashion on 14 March. Analysis of data shows partial failures starting some hours prior to the initial NetBlocks alert.

This points to a different kind of attack or technical issue within Facebook’s data centres. The current study is based on 30,000 network measurements from 2500 global vantage points - locations from which we can observe network performance using probes.Īt each point in time and at each location, the round-trip time or latency, and any network failure information is relayed and aggregated to get a picture of internet access around the world in real-time.ĭata from the incident lets us rule out a global routing issue as the underlying cause, and NetBlocks also hasn’t observed the kind of spike in latency prior to the outage usually associated with a DDoS attack. Work is ongoing to determine the likely cause of the incident.Ĭonfirmed: Analysis of global network data shows Facebook, WhatsApp, Instagram and Messenger down globally for an estimated 60% of users incident ongoing #FacebookDown ⬇️ /Osa5hfAdIo

Some users remain able to access the services, although availability has fallen to around 40% globally. Analysis of worldwide network measurements across several Facebook, WhatsApp, Instagram and Messenger servers shows signs of a partial global outage in effect as of 14 April 2019.
