Understanding Telegram Data Centers (DC) and Account Allocation

Conclusion

Telegram account allocation is closely linked to its Data Centers (DC). The country/region a user selects during registration determines which Data Center their account belongs to, and this cannot be changed once registered. Understanding this information is crucial for optimising your Telegram user experience.

Telegram Data Center Overview

Telegram has established multiple Data Centers (DCs) globally to support its services, specifically including:

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

How to Confirm Which DC Your Account Belongs To

1. According to Telegram's official documentation, the DC an account belongs to is usually determined by the IP address at the time of registration.
2. In practice, the DC an account belongs to is determined by the country/region selected during registration. For example, numbers starting with +86 are mostly in DC5, while numbers starting with +1 are typically in DC1.
3. The DC is fixed at the time of registration and cannot be changed. Even if you change your mobile number, the DC will not change. To change your DC, you must delete your existing account and register a new one.
4. You can query your account's DC using the following bots:
   • @Sean_Bot
   • @KinhRoBot
   • @nmnmfunbot

Significance of Setting Up Proxy Policy Groups 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 instance, if your account is in DC5, regardless of which DC the recipient's account is in, viewing media you send will be downloaded from DC5. Conversely, if the recipient's account is in DC1, viewing media they send will be downloaded from DC1.
3. After understanding the above two points, you'll find that setting up a separate proxy policy group for Telegram doesn't have much practical significance. This is because group members might be distributed across different DCs, and setting a proxy policy group would only increase download latency, but the perceived difference isn't significant.

Other Information

DC5 has poor stability, thinking of switching to DC1? However, DC1 and DC4 also frequently have issues 😂
