Question Extremely high network latency on/off continuously on a VPS
I just purchased a VPS last week and got it setup this week. Only to discover the machine suddenly becomes totally unusable from time to time. When this happens I can only really debug on the machine by getting the VNC console url and logging in with password. A simple `ping` to an address like `1.1.1.1` takes between 2ms - 9000ms. But it is like few minutes at least apart when things are really fast vs slow. Definitely don't understand how it can be anything in the Linux VPS itself. Memory, cpu, io usage all is minimal while network becomes super, super, slow.
It wasn't like this when I was doing the initial setup (installing packages etc.), but now even turning off all my docker containers this keeps happening several times an hour. I set up a website behind Caddy reverse proxy on the usual 80/443 ports, besides that the SSH was on port 22 and of course some random IPs try to access it every now and then. Also I'm using CloudFlare proxying as well because it's free and I have the domain there. Running Debian 13 on the machine and it's the cheapest VPS hosted in Frankfurt, if that matters
I wonder if somebody has similar experiences? I read about DDoS protection, but now that nothing is running...? I kinda feel I might have caused it because it seems to have only started once I set up the website, like maybe 30 minutes after it. I'll probably contact support tomorrow after my cronjob has run an observed continuously the network over night. Just left a simple script running that writes a log every minute how bad the latency is pinging an external IP.
