SRVPROBA, SRVPROBB & M7TEST
If you have seen SRVPROBA, SRVPROBB, or M7TEST in YSF reflector logs, this page summarizes what has actually been observed and what remains unconfirmed.
What are SRVPROBA and SRVPROBB?
SRVPROBA and SRVPROBB are short client identifiers that have appeared in public YSF reflector logs. In the records reviewed by YSF Live, the two names showed a repeated automated-looking pattern: a connection appeared, remained briefly, and then disappeared without normal voice traffic being observed.
The SRVPROBA/SRVPROBB traffic reviewed by YSF Live came from 43.159.193.48, an address announced by AS132203 (Tencent Cloud). That identifies the network carrying the traffic; it does not identify the person, organization, or software operating the client.
What is M7TEST?
M7TEST is another test-style identifier that has appeared in YSF reflector logs. It has been discussed alongside SRVPROBA/SRVPROBB because of similar questions from reflector operators, but the available evidence does not establish that the names are controlled by the same operator or system.
Are SRVPROBA, SRVPROBB, or M7TEST part of YSF Live?
There is currently no verified evidence tying these identifiers to YSF Live. YSF Live does not intentionally hide its identity. Monitoring tools should be transparent, and YSF Live's own production traffic is intentionally identifiable.
Timing, naming patterns, or a cloud-hosted source can suggest automation, but those clues are not enough to prove who operates a client. Reliable attribution would require matching source and destination logs or equivalent process/network evidence.
What YSF Live can say with confidence
- SRVPROBA and SRVPROBB have been observed connecting from 43.159.193.48.
- The reviewed connections followed a short connect/hold/disconnect pattern and did not show normal voice traffic.
- The source IP is cloud-hosted infrastructure, which does not by itself identify the operator.
- M7TEST is a separate test-style identifier seen in reflector logs; ownership has not been verified.
- No verified evidence currently establishes that SRVPROBA, SRVPROBB, or M7TEST are YSF Live clients.
Why this page exists
These names have generated questions among YSF reflector owners. This page is meant to keep the public record clear: separate observed facts from assumptions, document what YSF Live can verify, and update the explanation if stronger evidence becomes available.
