• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • (Plesk for Windows):
    MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

Issue DDOS attack

Bogdan1

Regular Pleskian
Hi,
I have VPS provided by OVH.
Today my sites went down and cloudflare started to show 522 error.
I followed steps from here How to diagnose DDoS attack on a Plesk server and the results are more than 400 connections, by multiple ip addresses(not more than a 200). So I bought (D)DoS Deflate Interface and blocked all countries except 1.
But this didn't help, so waste of money. It blocked 120 pages of ip addresses, sites are still down and it still shows hundreds of connections by hundreds of ip addresses.

Any ideas what to do? I thought DDOS won't be a thing for me with OVH and its Anti-DDOS thing would ...

PS: Plesk Admin works as normal but all hosted stiles are down ...

Code:
[root@vps520565 ~]# ss -tan state established | grep ":80\|:443" | awk '{print $4}'| cut -d':' -f1 | sort -n | uniq -c | sort -nr

So basically if someone is attacking 1 customer's websites, it downs all of the websites hosted on the server. How do you guys handle that?
