  • 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.

What's the problem with updates.drweb.com? For weeks we've been getting frequent update errors. Yet the server itself is online, but it responds with a 503 error. Example:

Email message:
Code:
/etc/cron.daily/drweb-update:
ERROR: Dr.Web Updater: failed to download files !

On the console:
Code:
[root@...]# curl -I updates.drweb.com
HTTP/1.1 503 Service Temporarily Unavailable

Manual downloads of the virus definition file work fine, example:

Why don't the nightly downloads work reliably any longer? There have been times in the past when they had scheduled maintenance, but this has been going on for weeks now.
