    i use google dns in my servers.

    this day my isp have some network problem for connecting google dns and my server like insane.
    ping normal but if i try connect ssh or sftp it wait like 10 min. after connected no problem.

    Please try other nameservers in /etc/resolv.conf.

    Lots of services do DNS lookups, that's why your system was so slow.
