  • Hello Gopal,

    Thank you for contacting us. We don't offer a speed in Azure as it goes through the internet. There are many parameters involved here like location, your internet bandwidth etc.

    Which location is the storage account hosted?

    From where are you accessing this storage?

    Did you do a tracert to the destination url to see what are the hops in between and what is the latency you get.

    Adding a similar thread for your ref:-

    Regards,

    Dipin Mathew.

  • Thanks. Did trace-route and below is the output (masked the local ips, since their latency is low and does not matter).

    Till hitting the Microsoft servers at 104.44.225.108 it looks fine. Beyond that it is going wild (in the*.ntwk.msn.net) with 100+ms latency

    =========================================

    Rest of them are all request timed out. 

    BTW, what is 25.149.65.195, doing here. The ip lookup says, it is UK Ministry of Defence. Wow, what is happening. 

    Anyway, it is clear that inside the MSN network there is some problem. The blob is at 40.78.112.72
