How to validate routing of last mile in the context of SAP Cloud for Customer
It is possible to validate routing of last mile, using the command “tracert” to identify the route that is used to connect to the Akamai server and with this understand if the network packages are traveling to other regions or countries which could be adding overhead and might require closer look of the network administrators or ISP. By example:
- Use the tracert command to get IP for each of the hoops or routers involved in the routing
- Once we have the IPs we can use any of the IP geolocation services mentioned here to get the location and use information from the tracert to look into the latency

It is important to mention that different tools use different geo database and results could be different due to outdated database, it is recommended to get geo location information from different sources.
May I ask you a question? I used the command “tracert” to identify the route of an internal system. The result is weird, because many entries show 'Request timed out' and the character of '*'. I have made a screenshot, you can see it from the attached image.
Do you know why I have this result? I was in office when did this trace with the corporate network. Is it due to the firewall?
