Several factors can result in poor TeraCLOUD performance.

Possible Causes

TeraCLOUD operates over the Internet, so various networks must be traversed to reach it from your local environment. Because of this, it can be difficult to determine the specific cause of overall poor performance, but the following may help with a simple diagnosis.

  1. Are load times slower than usual for sites other than TeraCLOUD? Are there any problems connecting?
    • If websites other than TeraCLOUD are also slow to load or respond, there may be an issue with your internet connection.
  2. If only connections to TeraCLOUD are slow
    • The following issues could be the cause:
      • Congestion on TeraCLOUD systems. If congestion continues for an extended duration, a notice will be posted on this website.
      • Excessive load on your device. Please check your device's resource usage for signs of a problem.
      • A problem with the route between your Internet Service Provider and TeraCLOUD. In this case, action is required between your provider and TeraCLOUD, and the issue cannot be resolved by you.

In the second case, when the cause is internet routing between your provider and the TeraCLOUD network, it is technically possible to improve speeds by establishing direct connections between your provider and us. However, because this must be done with the cooperation of your Internet Service Provider, such issues cannot be resolved by you or us alone.

Trace your route to TeraCLOUD

By providing the following information, you can help us better understand the situation between your Internet Service Provider and us. Typical TeraCLOUD usage patterns involve frequent transmission from the end user to TeraCLOUD, so we require information from your end for an accurate representation.

The traceroute command (tracert in Windows) shows the network route to a remote host, allowing investigation of intermediate routers along the route. While not directly related to bandwidth (upload and download speeds), the response times shown for each router can be used in a simple evaluation of network capabilities.

How to use traceroute

On Windows systems:

In this example, we run tracert to yura.teracloud.jp. Adding the -d option performs the trace without DNS resolution.

C:\>tracert -d yura.teracloud.jp
Tracing route to yura.teracloud.jp [103.49.141.114]

Trace complete.

On Unix-like systems:

Here we run traceroute to yura.teracloud.jp. The -I option specifies that ICMP will be used, and -n conducts the trace without DNS resolution.

$ traceroute -I -n yura.teracloud.jp
 1  **.**.255.254  5.924 ms  5.743 ms  5.838 ms
 2  **.**.158.190  7.037 ms  6.303 ms  6.442 ms
 3  **.**.77.125  5.839 ms  5.843 ms  11.042 ms
 4  **.**.77.225  5.763 ms  5.844 ms  5.846 ms

 7  **.**.140.193  9.311 ms  9.378 ms  9.302 ms
 8  **.**.140.18  12.211 ms  12.236 ms  12.826 ms
 9  103.49.141.114  12.692 ms  12.836 ms  12.279 ms

The values shown in milliseconds (ms) are each router's response time, representing the time taken to travel to the given router and back.

If response time increases greatly at a particular point, it is likely that an issue with the internet route is causing performance problems.
