Liquidweb is down? (DDoS)




Posted by Samuraid, 03-11-2008, 08:12 PM
Both my VPS and the main LiquidWeb.com site seem to be down or experiencing huge packet loss. Normally there is a second router hop after "core2-ge2", so maybe one of the distribution routers is down? Anyone else seeing this? Last edited by Samuraid; 03-11-2008 at 08:15 PM.

Yep, another DDOS =( I spoke with them on the phone about it over 30 mins ago.

That's unfortunate. DDoS is a pain for anyone.

What is weird about that is that our DSL from Qwest cannot reach the main site or any servers on it, but Comcast cable can with no problems. Anyone else seeing this kind of behavior?

It's been down for about 5 hours for me. Lost hundreds of dollars already. Samuraid, are you in California like me?

We have also been told its a DDOS, I am now doing the waiting game...

I am experiencing the same issue. I am in Albany, NY and cannot access any of my websites on my vps including LiquidWeb.Com but remoteing to my home in Alabama I am having no problems accessing any of my servers. Absolutely awful.

I am in Iowa and it doesn't work from my Qwest DSL modem. But, from a cable modem, it runs just fine. Also, my monitoring service says that everything is running just fine. Strange.

I just talked to a tech over there and he has confirmed it's a DDoS.

I called 2 hours ago, and they said it has something to do with AT&T.

Posted by skfox, 03-11-2008, 09:38 PM
I hear all of you saying that it is a DDOS, but how can that be when it only seems to be (so far) effecting Qwest users?

I said DDoS because that's what the tech who I spoke with on the phone told me?

Posted by Samuraid, 03-11-2008, 09:41 PM
Yes. Although, I can access the site fine from home (Verizon), my work connection cannot (AT&T).

Sorry cricex, I should have posed that question better. If a datacenter has multiple inbound connections, could a large amount of traffic coming through one of them cut off people that are also on that provider? I thought the design of the net allowed for such re-routing. I'm sure that a DDOS (or provider cut-off) is occuring, I was just trying to understand how that could cause the effects we are seeing.

This is an educated, unconfirmed guess, so take it for what it's worth........ AT&T doesn't have blackhole communities readily available as other carriers usually do. Therefore, if infact it's a DDoS, which we have no reason to suspect contrary to what the callers have been told, they're likely struggling to uncongest their AT&T circuit. Therefore, the paths that take this carrier (link to them) inbound, will experience poor to no connectivity, while those on Comcast for example, are still able to access sites hosted at LW, as Comcast is most likely using L3 Transit (possibly still GLBX). Hope this helps.

Exactly, its a router issue. not dDOS. Why would a kid dDOS liquid web?! There is no profit from it. Why would they dDOS just one router? Think logically people.

It appears that I can access Liquid Web again. It will be interesting to see if they announce anything.

Posted by blockcipher, 03-11-2008, 10:05 PM
My server is online, for the time being.

Hello Everyone, Thank you for your patience as we investigated and corrected this issue. As some of you are aware we had a routing error today that caused connectivity issues for approximately 5% of peak traffic for less than 3 hours. If anyone has experienced an outage I personally apologize and please contact me so that I may provide you an SLA credit. At approximately 6pm we experienced an extremely large, and unfortunately extremely frequent, DDOS attack. Normally this would not have been a problem but it appears that this may have exhausted a memory problem in one of our Cisco core routers. Our other routers continued to work properly but the affected router was unable to reach a small portion of IP space. This is why some people saw that it worked fine from home but poorly from their office. It appears that this affected about 5% of our IP space based on our early statistical analysis. We replaced the affected card with brand new standby equipment and everything seems to be stabilized now. I'm going to be completely honest here guys, I'm not the Liquid Web Cisco/DDOS/Networking Guru, so please go easy on me, if you need a more technical explanation just let me know and I can get you in touch with someone on that team. We sincerely apologize for any downtime that you or your customers experienced as a result of this connectivity issue. If you would like to discuss anything please let me know.

Good to see travis

Working fine.

How many servers do you have with Liquidweb?
