  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

High ping loss and connection problems

M

MarcSerra

New Pleskian
As you can read on centos forums we got connection problems on 1 of our servers. Making an horrible experience work with our websites, plesk panel, ftp, and all of other services.

Ping results from an office connection to the server (windows machine)...
Code: 
sent = 946, received = 530, lost = 416
    (43% lost),
Times:
    Min. = 48ms, Max. = 125ms, Med. = 54ms

From another office connection to the same server (linux machine)...
Code: 
    10 packets transmitted, 4 received, 60% packet loss, time 9012ms
    rtt min/avg/max/mdev = 0.240/0.256/0.296/0.030 m



If we ping from our server to the internet (google) got variable results...
