Telegram’s Unstable Singapore Data Center Triggers Massive Outage Across Asia and Oceania

Telegram's DC5 data center in Singapore went offline on September 8, and millions of users across at least seven countries lost service. The outage lasted just over an hour and triggered nearly 4,000 issue reports in Singapore alone. Roughly 50% of the user reports involved total app functionality failures, and 40% involved broken messaging capabilities. Telegram's four other global data centers operated normally during the disruption. The DC5 hub has a documented history of instability, and Chinese-language Telegram groups built their own informal status tracking systems to monitor it.
