Telegram Reveals Data Center Distribution and Issues
Key points
- Telegram has five data centers in different locations.
- DC5 is frequently down, affecting users in China.
- DC2 and DC3 appear to have no users currently.
Overview of Telegram's Data Centers
Telegram operates five primary data centers (DCs) globally named DC1 to DC5, located in Miami, Amsterdam, and Singapore. Each user account is linked to a specific DC at registration, which remains fixed regardless of the user's location.
Issues with DC5
Among the data centers, DC5 has gained notoriety within the Chinese user community for its frequent outages. Users connected to this DC often face connectivity issues, leading to discussions about its reliability. When DC5 is down, users are unable to access Telegram services, resulting in noticeable frustration.
The Mystery of DC2 and DC3
Curiosity about the distribution of users across the DCs has led to the development of a bot that can identify which DC a user is connected to. This reveal has shown that most users are divided among DC1, DC4, and DC5, with a conspicuous absence of users in DC2 and DC3.
Speculations about DC2 and DC3
While some users speculate that DC2 and DC3 are inactive, others suggest that they may serve as backup or subordinate data centers. Analysis of user data reveals that DC3 likely has not accepted new registrations since around 2020, while DC2 is believed to still host a reasonable number of active users.
