Users worldwide have reported problems accessing several popular artificial intelligence services, including OpenAI’s ChatGPT, Claude, Grok and Google Gemini, as well as the software development tool Cursor. The near-simultaneous timing has raised questions over whether the disruption originated in shared online infrastructure, although no common cause has been confirmed.
Data displayed by Down Detector showed a sharp increase in problem reports affecting several services during the same period.
Attention turns to shared infrastructure
The timing of the disruptions has shifted attention beyond the individual AI platforms and towards the infrastructure used to host services and carry internet traffic.
Among the areas under scrutiny are hyperscalers, companies operating large-scale cloud infrastructure and data centres, including AWS and Microsoft Azure.
Many digital services rely on these systems either to host their data or to manage traffic through shared interconnection points.
AI-dependent developer tools also affected
The disruption was not limited to AI platforms themselves.
Problems were also reported with software development tools such as Cursor, whose operation depends on APIs provided by companies including OpenAI and Anthropic.
This has added to indications that the disruption may be affecting more than one level of the technology supply chain.
Possible wider internet disruption
Problems were reported during the same period across services that are neither directly connected nor exclusively linked to artificial intelligence.
One possibility being examined is a wider disruption affecting the routing of international internet traffic.
The issue could be linked to Tier-1 transit infrastructure, DNS services or shared interconnection points used by multiple online platforms. No single underlying cause had been confirmed at the time of publication.
