  • Very slow tunnel

    From Victor Sudakov@2:5005/49 to All on Mon Aug 5 12:58:38 2019
    Dear All,

    As you probably know I'm using an IPv6 tunnel via HE. Recently my IPv6 connectivity has become *very* slow, any ideas how to debug it:

    Sorry ... I do not think that there are many debug possibilities.
    Probably the easiest would be to get a second tunnel from another tunnel provider and see if it works better.
    Try to ping the possible tunnel servers and take the one with the lowest delay.
