It has been observed that PT players who do not use PCDN have experienced upload speed limitations, with upload speeds dropping to 1M. Specifically, PT uploads are completely unable to function. This issue also affects RDP remote connections. Furthermore, the company's file transfer process has also been impacted, making it impossible to transfer files. Speed testing websites, on the other hand, have not reported any issues. The matter has been reported to the telecom company and a technician has been dispatched to conduct an on-site speed test. A formal complaint will be lodged with the State Administration for Market Regulation (SAMR) after the results are announced.
