DDoS Protection from Psychz Networks: your experience?

Psychz Networks staff informed us today that it is impossible to have substantial, sustained and legitimate inbound traffic, in more than 1 or 2 threads, to a single destination (server) behind your DDoS protection, even if this traffic is a fraction of its total capacity and allows DDoS protection.

This can be easily replicated by downloading any large file 3 times or more simultaneously. For example :

https://speed.hetzner.de/10GB.bin

Here is an example of the result:

In this example, the total server throughput is less than 1 Gbps (link speed) and is connected to our network equipment, which has 10 Gbps connectivity to Psychz Networks (with less than a few hundred Mbps of background traffic ). 40 Gbps of DDoS protection are allowed. A null route was produced (as verified by a route plot and confirmed by Psychz Networks staff) after approximately 30 seconds of sustained traffic (4 wires each at about 20 MB / s each). The null route lasted about an hour. No email or ticket is created to warn us. This experiment was repeated several times in different systems.

Our clients legitimately expect to be able to fully use their 1 Gbps network port and will not face a null route under any circumstances if the total incoming traffic to our equipment does not exceed 40 Gbps.

Psychz Networks staff kindly reproduced this exact scenario and observed the result detailed above. The answer we receive is very clear: this is the normal and expected result. The only solution is to opt for DDoS protection.

We really wonder if we are being selected. This does not look good at all. We also wonder how our customers are supposed to be protected from an incoming volumetric DDoS attack when they cannot survive 1 Gbps of legitimate incoming traffic. A case in which an attacker would send 1 Gbps of traffic sustained in 2 or 3 TCP sessions would eliminate a host behind the 40 Gbps DDoS protection of Psychz Networks. Psychz Networks could not answer this last question.

What has been your experience with Psychz Networks DDoS protection? Are you able to reproduce our case?

To be honest,

Hivelocity vs Caliza vs Psychz

I have been with Limestone for almost 6 years, they are quite good, without major problems so far, their support has always been very receptive. For some reason, I always had the idea that its growth has stagnated, p. The hardware they offer is a bit outdated and doesn't have so many options. Also, your network seems to have downtime from time to time, so I have been thinking about moving to another provider, preferably one with multiple DCs in the US. UU.

I limited my search to HiVelocity, Psychz and obviously I stayed with Limestone. HiVelocity has many hardware configurations, DC, and seems to be a much larger company than Limestone: the rates seem similar. Psychz seems good, but there is something odd about them, that is, there are not many reviews, complaints about technical support in India (so it is probably not as receptive) and also not sure of its network.

I run a VPN service, so the network (uptime, latency, speed, packet loss) are the most important factors for me. We saw many people commenting that the HiVelocity network is rock solid and excellent. How does it compare with limestone and Psychz? Among the 3, which one is the best? network, support, intelligent hardware?
