Why transferring files from DO to Linode is so slow recently?

My DO server is located at Singapore and my Linode server is located at US. The transfer speeding using scp was normally 3-4 MB ago, but now it's only around 100K-200K. Does anyone have a clue?

  • Could you provide a traceroute from one host to the other? It might shed some light on what is happening here. Checkout this article for some more info on diagnosing network issues:

    How To Use Traceroute and MTR to Diagnose Network Issues

    by Justin Ellingwood
    In this guide, we will discuss how to use traceroute and mtr to diagnose network issues. These tools and utilities will provide a good overview of what stage of the network is causing problems. You can tell if an issue falls within your realm of influence or whether you need to contact the owners or maintainers of alternate networks.
  • Thanks a lot. I use traceroute and here's the full routes. I read the article and it says 'If your traceroute dissolves into some asterisks (*), there is a problem with the route to the host'. In my case there are 16 asterisks. Does it mean there is a big problem along the routes?
