There are many reasons that affect the slow network speed, including the situation of the other site (server configuration, line operator); Client problems: such as the user's computer configuration, whether the computer is infected with viruses, etc. Visiting foreign websites will be affected by international export bandwidth and Internet problems. So the customer service with slow network speed can hardly be solved online. Customer service online can only refresh the account, but this operation only reconnects the account after offline, which basically does not help the network speed; Maybe you said 100 10.
