Traceroute
The path packets take from our server to the target, hop by hop, with the network (ASN) each router belongs to.
Frequently asked questions
What do the asterisks mean?
An asterisk is a probe that got no answer in time. Many routers ignore or rate-limit traceroute probes; if later hops answer, the path is fine.
How do I find where the slowdown is?
Look for the hop where latency jumps and stays high for every hop after it. A jump that disappears at the next hop is just a router answering slowly, not a real problem.
What is an ASN?
An Autonomous System Number identifies one network operator, such as an ISP or a cloud provider. The ASN column shows which networks your traffic crosses.
