Understanding Telegram Data Centres (DCs) and Account Assignment

Conclusion

Telegram account assignment is closely linked to its Data Centres (DCs). The country/region a user selects during registration determines the data centre their account belongs to, and this cannot be changed once registered. Understanding this information is crucial for optimising the Telegram user experience.

Overview of Telegram Data Centres

Telegram has established multiple data centres (DCs) worldwide to support its services, including:

• DC1: USA - Miami
• DC2: Netherlands - Amsterdam
• DC3: USA - Miami
• DC4: Netherlands - Amsterdam
• DC5: Singapore

How to Confirm Your Account's Assigned Data Centre

1. According to the official Telegram documentation, an account's assigned DC is typically determined by the IP address used during registration.
2. In practice, the DC an account belongs to is determined by the country/region chosen during registration. For example, most +86 numbers are assigned to DC5, while +1 numbers are usually assigned to DC1.
3. The DC is fixed at the time of registration and cannot be changed. Even if you change your phone number, the DC will not change. To switch DCs, you must deactivate and re-register a new account.
4. You can query your account's assigned DC using the following bots:
   • @Sean_Bot
   • @KinhRoBot
   • @nmnmfunbot

The Significance of Setting Up a Proxy Strategy Group for Telegram

1. The DC your account belongs to determines where your data (such as messages, images, files, etc.) is stored. When you send media in private chats or groups, recipients need to download this content from your DC.
2. For example, if your account is in DC5, regardless of the recipient's account DC, viewing media you send will result in a download from DC5. Conversely, if a recipient's account is in DC1, viewing media they send will result in a download from DC1.
3. After understanding these two points, you'll realise that setting up a separate proxy strategy group specifically for Telegram has no practical benefit. This is because group members may be distributed across different DCs, and setting up such a group would only increase download latency, with no significant noticeable difference.

Other Information

DC5 has poor stability. Want to switch to DC1? However, DC1 and DC4 also frequently experience outages 😂.
