Google outage: developments after the September 4 disruption
See our initial news update on the outage here.
On September 4, 2025, millions of users across Eastern Europe faced a major Google outage. Core services such as Search, YouTube, Gmail, Maps, Drive, and Gemini went offline for several hours, leaving many organizations unable to operate normally.
Timeline of events
Sept 4, 2025 – The outage began around 07:00 GMT (10:00 local time) and lasted several hours. Bulgaria, Turkey, Greece, Romania, and Serbia were among the most affected countries, with reports also coming from dozens of others.
Sept 5, 2025 – The Google Workspace Status Dashboard listed short-lived incidents in Gmail, Drive, and Calendar, described as localized and resolved. However, the scale of user reports suggested broader disruption.
Sept 6–8, 2025 – Analysts pointed to potential technical causes such as infrastructure failure or routing errors (BGP/DNS). Several ISPs and mobile operators also experienced difficulties, likely due to their reliance on Google Cloud.
Sept 9, 2025 – A Middle East–linked hacker group claimed responsibility for the disruption, alleging an attack on Google’s servers. These claims remain unverified, and Google has not issued any official explanation.
Broader impact
The incident once again highlights the risks of over-dependence on a small number of global providers. When platforms like Gmail or Maps go down, businesses and public institutions are cut off from essential tools. This underscores the importance of contingency planning, backup solutions, and diversified infrastructure strategies.
Update – September 17, 2025
Several authoritative media outlets, including Reuters, confirm that Google services (Search, YouTube, Gmail, Drive) were disrupted across Turkey and parts of Eastern and Southeastern Europe on September 4, 2025.
Authorities have requested a technical report from Google, but as of now, the company has not provided an official explanation. Services were restored the same day, yet the root cause remains unknown.
DIAMATIX Expert Perspective
“This incident proves that even the world’s largest tech providers are not immune to outages. Whether technical or malicious in nature, organizations must be prepared with resilience strategies, redundancy, and business continuity plans. Our recommendation to clients is clear: build architectures that reduce dependency on a single provider.”
