Network misconfiguration on a low-cost VPS
While investigating the source of excessive inbound traffic on a fresh KVM VPS that was essentially idling (with the SSH port closed), I discovered quite an amount of local ethernet traffic arriving from neighboring VPSes. Surprisingly, it was conversations not belonging to my VPS, between the neighbors and the gateway. I have another KVM VPS (even slightly cheaper), and after the same investigation, only minimal usual broadcast traffic was observed.
So, the questions is: is it normal for sub-$14/year VPS to have such a network (mis)configuration? Has anyone investigated the issue? Was the issue promptly resolved by the provider, or it's better not to waste time and switch to another provider?

This can happen with $100+ / month service.
Upload packet trace to prove your point.
When we complained about a network flooding affecting our sub-$14/year VPS with valid proof, the offending traffic was stopped promptly.

Not normal but shit happens.
Well, I don't think other users from that provider would approve their IPs revealed, so "trust me bro."
It's not about flooding, it's about security.
Then bring this to the provider attention.
Could happen because they don't know or they don't care or someone forgot to do something when quickly setting up new BF/CM node.
Or they want it to happen so you can run out of bandwidth faster and they can suspend the server earlier aka sell even moooooooooooar.
Without naming or messaging provider you will never know.
What kind of security? Most of the times it's clients that send some kind of shitty broadcast because missconfigured software so it's not like they care about security in first place :-D
The bandwidth used is not so big, it's was just that caught my attention.
I thought it's possible to snoop traffic for all subnet there... Then I need another VPS there to figure out is my traffic visible on other VPSes ;-D
?
You can normally see all the IPs a provider has..
