Let’s face it – the world tends to be a very hostile environment and the internet is not much different.  From viruses and trojans to distruption of service attacks – it happens all day every day and it is only a matter of time before it affects you.  I have personally dealt with two DoS attacks in the last two weeks and both for very different reasons although the end result is about the same.

Last week the DDoS, or distributed disruption of service, attack was motivated entirely by financial gain for the attacker.  The attacker had previously attacked another hosting company called A Small Orange and had attempted to extort $7,000 from the company to stop the attack.  ASO did not bow to the demands of the attacker and simply worked to filter out the attack and return service to their customers.  While some of ASO’s customers were not satisfied, many times when a provider is put in this situation there is not much that can be done.

The attacker moved on from ASO to my company and sent a message to our sales department informing us that we were next.  The attack began about an hour later and peaked at about 4.5GBPS which is enough to  bring down most small data centers in their entirety however our data center SoftLayer Dallas was able to filter out the attack within 10 minutes to restore full service.  The attacker subsequently moved on to their next target which was VectorLevel who was hosted with Colo4Dallas at the time.  The attack at VectorLevel brought Colo4Dallas to it’s knees until the attack was null-routed at C4D’s upstream provider.  At the time of this writing Colo4Dallas’ web site was unreachable and as such I am not directly linking to it.

Fast forward a week and a half and another one of my servers was under a new attack from a new source.  This time the attack was not monetary and the goal was simply to take a particular site offline.  The target of the attack was a fairly popular forum that centers around firearms manufactured by a particular company.  The forum has information such as cleaning and maintenance of the guns and in my looking over the site is nothing apparently negative.  My guess is that whoever wanted to bring the site offline was more of a “pro gun control” type of person.

This attack was a bit more difficult to stop as it was smaller and “flew under the radar” of our automatic filtering systems but was still large enough to cause intermittent connection issues over the period of about two hours.  We worked to filter out the attack however whoever was administering this particular attack was doing a pretty good job of countering the counter-measures were putting in place to mitigate the attack.  Ultimately we were able to fully mitigate the attack after quite a bit of work and effort.

It seems that there are malicious people out there whose only goal is to cause harm and to disrupt the services of others.  If you do find yourself in a situation where your web site or hosting service is being disrupted by a DoS attack please do be patient with your provider and understand that there isn’t always something that can be done to fully mitigate the attack.  If your provider is able to restore full service to you within a fairly short period of time (less than 2 to 4 hours) you should consider yourself lucky as many DoS and DDoS attacks can last days if not weeks.

The issue is that the Michael Jackson funeral is the largest web event in history. This is causing sluggish response times everywhere.

We have had several clients submit tickets saying things such as “My site is loading slowly or not at all” and in my testing I have found that it is difficult to make connections across the country depending on what backbone your internet service provider is using.  It seems that Level3 and RoadRunner are having some trouble with the amount of traffic being transferred across their backbones where as I am seeing beautiful performance out of the Comcast backbone myself.

Upon asking for further detail from our datacenter, SoftLayer, this is what the representative had to say:

We are getting reports of sluggish response from all locations. There is no point of origin. It is internet wide.

If you are browsing the internet right now and everything is running smoothly then you can consider yourself lucky.  If you do run your own web site and you are having trouble connecting to it or you are receiving reports from your clients that your site is down there isn’t much you can do but tell them that the internet is extraordinarily congested due to the Michael Jackson funeral today and that we will all just have to wait this out.

There is also a thread that has been started by a user having issues with the internet over at the good old WebHostingTalk.com discussing that they are having issues connecting to WebHostingTalk.com where as other users are reporting no issues at all.  There is no definite way to tell if you will or will not have problems and you may have problems visiting one site while not having problems connecting to another.

Are you having trouble connecting to your own site or a site that you frequent?  Post a comment and let us know!
