OVH anti-DDoS protection
The pre-firewall is the first component of our VAC system. It is fully managed by OVH, and applies rules that define filters directing data packets to the Firewall Network see below.
These rules are applicable to all OVH solutions. When a DDoS attack is launched, the pre-firewall manages part of the filtering, and sends the rest to the Firewall Network, which has customisable rules. Our pre-firewall is based on an Arista R, which can reach a communication capacity of This is the second component of the VAC. The Firewall Network is a solution that limits exposure to attacks from the public network.
It activates automatically as soon as a DDoS attack starts. Each rule is a specific authorisation you can use to optimise protection for your service. This firewall activates automatically whenever a DDoS attack begins, and you cannot deactivate it until the attack is over.
This is why it is important to keep your firewall rules up-to-date. You can use this technical guide to help you configure rules. Armor is the most advanced filter in our VAC, and mitigates the strongest attacks.

As an expert web solutions provider, OVH provides solid infrastructure with high availability for your hosting system.
The only thing you have to worry about is storing your files and bringing your website to life! As Octave Klaba stresses, this protection is essential because, "It's not a question of knowing if you need anti-DDoS protection but rather when you will first be the victim of an attack. DDoS attacks aim to render your website unavailable by overloading the server's bandwidth or monopolising its resources until they run out.
The most common attacks are level 7 the highest levelwhich aim to overload the system with PHP requests. Today, alerts have multiplied and the risk of attack is greater than ever because the technology and tools needed to stage an attack are readily available.
Not only has the number of the recorded attacks increased - but their brute force is greater,ie,their potential to damage even the most solid infrastructures. Guaranteeing the security and durability of our customers' online applications has always been a priority for OVH. Over the years, we have experimented with ways of anticipating, managing and counteracting these problems. As such we have been able to develop intelligent and robust tools capable of handling massive attacks. This tools features on our ranges of dedicated servers and Cloud products.
These tools have been adapted and transferd over to other products which required them, such as our Web Hosting services. Previously, we often had to suspend websites flooded with requests, in order to prevent the situation from damaging the entire service and affecting other customers.
It's an exclusive combination of techniques which analyse your traffic in real time and at high speed. They detect and intercept attacks automatically, while letting legitimate requests pass through.
In addition, the load balancing is even better with the introduction of PHP-FPMenabling improved server responsiveness. As a result, there is no longer any risk of the service being saturated.

A DDoS attack aims to render a server, service, or an infrastructure unavailable by overloading the server's bandwidth or monopolizing its resources to the point of depletion. During a DDoS attack, a multitude of requests are sent simultaneously from multiple points across the internet. The intensity of this "crossfire" renders the service unstable, or even worse, unavailable. There are three major ways DDoS attacks make your site, server, or infrastructure unavailable:.
Bandwidth: this type of attack consists of saturating the server's network capacity, rendering it unreachable. Resources: this type of attack consists of depleting the machine's system resources, which prevents it from responding to legitimate requests. Exploitation of Software Fault: also called "exploit", this type of attack targets a particular software fault either to make the machine unavailable or to take control of it.
ICMP broadcast attack usurping the source address to redirect multiple responses to the victim. Mass sending of TCP connections requests to a large number of machines, usurping the victim's source address. The bandwidth of the victim will be saturated by the responses to these requests. Mass sending of DNS requests usurping the source address of the victim, to a large number of legitimate servers.
As the response is more voluminous than the question, an amplification of the attack follows. Also called "Ping Flood, mass sending of packets including the response of the victim, which has the same content as the original packet. Sending of TCP segments that voluntarily reference other segments that will never be sent, which saturates the victim's memory.
Sending of UDP datagrams that voluntarily reference other datagrams that will never be sent, which saturates the victim's memory. Internet-based services are used without any problem. The traffic passes through the backbone of our network then arrives at the data center.Mitigation refers to the methods and techniques put in place by OVH to contain and reduce the negative impacts of DDoS attacks on an infrastructure or service.
To do this, we provide VAC technology, which relies on a unique combination of techniques that perform three tasks. If a similarity is detected, mitigation is then triggered automatically. The analysis of characteristics is measured by packets per second, or in bytes over several protocols, including:. Channelling a DDoS attack requires a high capacity to bear the load. The VAC is activated simultaneously in all of these datacentres, so that all regions can combine their power and absorb the traffic.
Mitigation refers to the methods and techniques put in place in order to reduce the negative effects on a server or service targeted by a DDoS attack.
Mitigation consists of filtering traffic, so that only legitimate traffic reaches the server. The VAC, a technology designed by OVH, carries out several filtering tasks which each have their own specific purpose. The VAC diverts the traffic to analyse it, and only lets legitimate traffic reach the server. Anti DDoS. Mitigation Mitigation refers to the methods and techniques put in place in order to reduce the negative effects on a server or service targeted by a DDoS attack.

We really enjoyed the snorkeling and the boat ride. We especially enjoyed stumbling onto the festivals.
While in Norourland Eystra, stayed Daeli, we saw a Icelandic singer with a wonderful voice, Egill Olafsson in some ancient ruins at night that took our breath away. And while in Grundafjordur we saw a parade of four colors with music and fun afterwards until 11:30 pm. It was cold to us but we stuck it out. Myvatn Natural Baths were fantastic. We did not want to get out.

The people at Nordic Visitor in Iceland are terrific. The trip was well planned with good Accommodations and excellent sightseeing adventures. I would highly recommend Nordic Visitor. Also, Erla and Bjorg. Erla made all the itinerary and Bjorg greeted us at the Nordic Visitor office.
Bjorg spent an hour with us happily and professionally going over everything.
Uei and I returned to the U. I just wanted to tell you how much we enjoyed our trip and appreciate everything you did for us. Especially re-booking our hotels due to the volcanic eruption.
Iceland is a beautiful country and we hope to return in the future. Lots of options with complete flexibility. Communication with Erla (the travel consultant) has been fantastic. We enjoyed every second of our holiday.
The preparation from your side was so absolutely professional, so excellent and brilliant.
