CDN Server Locations of WPMU DEV CDN.

I have some questions about the CDN feature in Hummingbird. Last time I activated it we got a lower ranking on speed in google.
My guess is that the CDN is based in the US only? If not, what is the CDN Server Locations?

    Hi there, we did some testing with the CDN in place and notice a significant decrease in performance when we enable it.

    The first test (whitout CDN) the dom stats loading after about 5700ms~ and the avrg response time for the server to return css files is 450ms

    The second test (using the CDN) the dom starts loading after 8300ms~ and the avrg response time for the CDN to return the css files is 1.2seconds

    I done some more digging and i see it is indeed as i suspected using a US based server both in the network panel of chrome developer tools as in a trace route i have made i see the following server 151.139.244.25

    Below the results of my trace route
    
    tracert hb.wpmucdn.com

    Bottle Post Media S.L.U.,

    We have raised the issue with the CDN provider. I am forwarding their reply below:

    Thank you for reaching out!

    Basically routing it self is not something that we can invert, afterall ISP is the one who has final word on that.

    Most of ISP`s are choosing cheaper routes which results in behavior that you client is experiencing.

    I went ahead and performed 2 traceroutes from Madrid through different ISP`s :

    https://p.catchpoint.com/ui/Entry/PW/I/EB0-Ea8q-Yq-I921-0-jVsEav91cn-AV0AR0-jVsEav91cn-Ea8q
    https://p.catchpoint.com/ui/Entry/PW/I/EB0-Ea8q-Y5-I764-0-jVsEav32IN-AV0AR0-jVsEav32IN-Ea8q

    As you can see those are routed to Paris which is expected.

    You can ask your client to try and check how it looks on different ISP, they should get a lot better results.

    Also often there is some maintenance which can cause bad routes but anyhow its really not something we can influence, so best would be to check with ISP they are using.

    Traceroute for me also consisted of only 5 hops.

    Best regards,
    Anton
