Connectivity issues 6/22/2012

We started losing connectivity this morning, maybe around 11:00 am -ish or so.  I narrowed it down to DNS.  Our local DNS servers were unable to contact OpenDNS (208.67.222.222, 208.67.220.220).  I did some Googling and found 75.75.75.75 and 75.75.76.76 as Comcast DNS.  Once I pointed our local DNS servers to these new addresses everything was....better.

 

I am still unable to ping the OpenDNS servers over our Comcast line.  I use OpenDNS at home and it is working fine there.

 

Another thing that threw me off this morning...my home computer (on Century Link) has been unable to connect to any of the resources on our Comcast line, but others have no problems.  I can't even get a ping response.

 

So, does it just so happen that our Comcast connection loses connection to OpenDNS servers at the same time that I cannot connect to work resources from home?  Or is there something somewhere that is broken that happens to affect both?

 

Thanks!

This is a problem with Comcast not OpenDNS.  Comcast is not directing DNS requests to other Comcast resources.

That is what I was suspecting.  Everything started working properly again just a few minutes ago so I think we're all good.

 

Thanks!

Would be nice to see everyones city either in the post itself or associated with the poster so we can see if its a related issue when there are outages. 

We are also experiencing outages today, had to fail over to our back up isp. For roughly the past 4-5 weeks our service has been degrading, we've traced everything on our end, had techs out, they all had some random theory, "fixed" the issue, left then the problem arises once again. We've had several tickets opened, then mysteriously closed, had techs no-show, and even go to the wrong location then close the ticket. "Business class", is typically a critical component to doing business and a major impairment when things dont work as they should. And should be trreated by the provider as such.

 

Our  web access is very crucial to our biz and we need 99.999% uptime. Tis is exactly why we have a back up isp, however the back up just may become our primary with the unreliablity we've experienced recently with Comcast. 

 

Our business partners need to prioritize our uptimes just as we do or we wont work with them, its that simple. Its not personal, its buisness.

This happened to us again this morning for little while. I noticed it at home before leaving for the office (around 8 am).  It started working again after about an hour.

 

We are in Burnsville, MN.
