And now they are down again, about 1/2 hour later .
Their forums load slowly, but do load. KnownHost-P (CTO) posted a bit ago that they are looking into the problem; tickets were coming in saying there were connectivity problems but their monitoring didn't flag anything.
I can every once in awhile ping my VPS, but the dropped packets are terrible. More problems at Colo4Dallas? DOS? We'll find out in due time. But I would guess that your server, like mine, is still up and running. Connectivity not so good, of course...
Is this a colo4dallas issue? Also had issues just a bit ago trying to get to a server their. Was getting major latency + packetloss at level3 hops. But it happened for less than 5 minutes. Seems working now.
Looks like all of colo4dallas (where knownhost's servers are at) is down as well. There had better be a refund from the uptime guarantee coming for this, as I have two clients that just signed up on my server and cant do anything. Makes me look bad.
This does look like a massive DDOS attack which affects more than just us. Even colo4dallas sites are not available. At the moment all that we have is a notification that they're aware of the issue and taking care of this
The issue doesn't appear to be with knownhost at all like they said. If you notice you will start to experience packet loss at the colo4dallas border router or shortly there after. I'm sure they will get everything worked out. Unfortunately downtime is part of the game despite what anyone tries to tell you.
DDOS I can handle, although I wonder who the bad apple is in the IP neighborhood that is getting attacked. If it were something as silly as what happened to media temple / dreamhost a few months back then I'd be more worried.
c4d has been having outages almos weekly the past 2-3 months. I *thought* they were rock solid but apparently not.
I sent them a DNS box back in june and I have at least 8-9 outages. I had one for almost 6 hours.
I have to disagree. I do not recall seeing anything like what happened today in the past. Within last couple months we had very few network related outages and all of them were resolved quickly. Colo4Dallas network is stable and reliable and, the most important thing - they're open for any kind of discussions and are very quick to resolve any issues that may appear.
UH-Matt - I'm sure you won't be disappointed
This is the first time I've had problems. Honestly this wasn't a problem with them. It was a problem with their DC which isn't their fault. It's hard to fault them for something that they can not control. Being mad at them over this is like being mad at your dog because it rains and you can't goto the lake.
We just got our first rack setup with C4D last week but have not yet deployed any hardware there. We did a lot of extensive research before making the decision and I went as far as meeting with Paul, Patrick and couple of other members of their team in person as well as touring their facility. I was very impressed with what I saw and the support tickets we have raised with them so far to get things setup have been answered promptly.
I can't speak for all sections of their network but we setup an Alertra tracker to monitor colo4dallas.com back in June and the first outage it recorded was earlier today lasting around 10 minutes. You can see this here: http://uptime.alertra.com/uptime.php...893&id1=843247
Their network design is extremely solid by running all of their routers in redundant pairs and providing HSRP drops to each rack. They have also recently added an InterNAP FCP box, which I saw when I visited the facility. One thing that I would like to see C4D deploy on their network is a device to help handle DDOS/DOS attacks better such as Cisco Guard and Tipping Point boxes.
All providers will have outages but it is how they handle it and communicate with their customers that is important. Any steps C4D can take to improve I am all for though. It looks like knownhost etc. are all loading now.
I have several accounts of them going down on a weekly basis. Believe it or not, it's not my problem if you wish to neglect this.
On several ocassions within the past few months Colo4Dallas has had issues. They were minor issues. For example, latency on their Level(3) link, etc. Once I believe they were down for ~ 10 minutes - some inbound routes were showing AboveNet which I believe they have been working on installing.
In late June they had a (D)DoS attack that resulted in about 20 minutes of downtime/massive sluggishess.
Few weeks after that they suffered from another (D)DoS attack resulting in sluggishness/timeouts for that evening.
Just recently they've been having on issues effecting certain routes. For example, to our office VPN there have been 'broken' routes, e.g. their router was unable to find a working route to our office VPN, even though everything was online on our side. This was fixed within a few hours.
You can say all you want here, but you are just quite frankly wrong.
I'm going stand by my side - which is full of facts. It's not just us, several of my friends have been customers/ex-customers and they are not happy with the uptime.
You and I both know that you aren't happy with the uptime at C4D. What you say in public here differentiates from that though which is quite strange IMHO.
