Cloudflare Inc. announced on April 24, 2026, that it is actively investigating a series of connectivity issues impacting its WARP and Zero Trust services specifically within the Bulgarian market. According to official status updates released by the San Francisco-based web infrastructure and security company, users in the region may encounter a significantly degraded internet experience or complete inability to connect to these specific services. The investigation was initiated following reports of service instability that began during the early morning hours of Friday.
The current disruption follows a period of intermittent instability earlier in the week. Between April 21 and April 23, 2026, Cloudflare recorded a surge in 5xx server errors affecting Cloudflare Access authentication requests. These errors prevented some users from successfully logging into secure corporate environments and applications protected by the company’s Zero Trust architecture. While those specific authentication issues appeared to have stabilized, the new connectivity problems in Bulgaria represent a distinct challenge for the company’s regional infrastructure.
Cloudflare’s Zero Trust platform is a critical component of its service suite, designed to replace traditional VPNs by providing secure, identity-based access to internal applications. The WARP service, which functions as a consumer and enterprise-grade VPN, relies on Cloudflare’s global network to optimize and secure internet traffic. In Bulgaria, these services are primarily routed through the company’s data center in Sofia. Cloudflare engineers are currently analyzing network routing and peering arrangements to determine if the issue stems from local internet service provider (ISP) handoffs or internal hardware malfunctions within the Sofia point of presence.
As of the latest update on April 24, Cloudflare has not provided a specific timeline for full service restoration but noted that its technical teams are working with local telecommunications partners to mitigate the impact. The company has not reported similar localized outages in neighboring Balkan countries, suggesting the issue is confined to Bulgarian network segments. Cloudflare’s Chief Technology Officer, John Graham-Cumming, has previously emphasized the importance of network resilience, noting that the company’s distributed architecture is designed to reroute traffic during localized failures, though Zero Trust tunnels can sometimes face unique latency or handshake challenges during regional disruptions.
The company’s status dashboard currently lists the Bulgarian connectivity issue as an active incident. Cloudflare maintains a significant footprint in Europe, with data centers in over 100 cities across the continent. For enterprise clients in Bulgaria, the disruption may affect remote work capabilities and secure data transfers. Cloudflare has advised affected administrators to monitor the official status page for real-time updates on the investigation’s progress and any potential workarounds for routing traffic through alternative regional hubs.
