Telegram BGP Route Leak Disrupted Access Beyond India’s Ban, Analysts Say

Summary
A temporary Indian Telegram ban coincided with an AS18101 route hijack that leaked globally through FLAG Telecom, disrupting access in the UAE. Analysts confirmed the route leak but said evidence does not establish deliberate sabotage; MTProto proxies can restore access
Key points
- India ordered a nationwide Telegram block through June 22 after allegations that the platform was used to distribute leaked NEET exam materials; a separate order disables message editing in India through June 30.
- Public routing data and network analysts reported that AS18101, registered to Reliance Communications, announced Telegram prefixes that leaked globally through FLAG Telecom (AS15412), disrupting access beyond India, including in the UAE.
- Doug Madory and other researchers confirmed the route hijack; RPKI validation and filtering limited how far the route propagated.
- Telegram CEO Pavel Durov alleged deliberate sabotage. Researchers cited in the article said the evidence does not establish intent and described a misconfigured domestic block leaking routes globally as more likely.
- Telegram’s built-in MTProto proxy can route around network-level blocking. The article cautions that proxy operators may see connecting IP addresses and connection times, though they cannot read messages.
