Interweb problems?

[JL8Jeff]

Anyone else having problems connecting to some interweb sites today? I can get to the smaller volume sites, but the busiers sites are all dead. It might be Comcast but I think it's the web.

I have comcast and can't get to a bunch of sites either including their own. This sucks I need to get to some of these places for work and I can't.

[Billfromnj]

Same problem for me, im on phone with comcast now to see whats up...

[91DropTop]

im having same issue big sites are extremely slow and i cant connect to AIM

i have comcast as well

I just tried getting on Mapquest before, and it didnt' work. I got this message -

Invalid URL
The requested URL "/", is invalid.

Reference #9.751293e.1207409710.0

All of my usual message boards I frequent on a daily basis are fine. FWIW, I have Verizon FiOS.

that's because comcast cache's a TON of websites, aka all of the heavily trafficked ones. When you go websites most of the time you aren't even truly going there. It's just commu-cast giving you info to cut down on their costs + bandwidth

Comcast is having a service issues in my area which is Essex Co. I'm sure it affects everyone with comcast. Weird that some sites work and others don't.

Weather channel, my real estate multiple listing site, comcast site all DOWN.

LS1.com, NJFBOA.org, Yahoo all good to go.

I was able to access Comcast.com and .net, along with weather.com with no troubles here, but I have Verizon interweb access. Still, what's up with Mapquest then?

[Anti_Rice_Guy]

I had an issue before but after waiting a few hours and resetting my router I'm fine. (been gone since ~8 am this morning when I had to check my e-mails)

No problems with the mapquest main page here, at what point are you having trouble? you could always use google maps

looks like you just had a typo.. couldn't tell you for sure though

[grandkodiak]

im in monmouth county and we have comcast, same deal... some sites work fine, some dont come up at all. aim has been dead the last few hours along with aol.com

[BonzoHansen]

Sounds like they had a DNS failure.

[firehawk1120]

don't know what that means but hope they fix it quick i need to work

[BonzoHansen]

As described to me the last time it happened, a the DNS servers basically point you to the sites. So when one goes down, all the roadmaps for the sites on those servers get lost. Think if your GPS went blank on way to somewhere you didnit know how to get to. I'm sure they are busting their humps on it.

[grandkodiak]

the internet is just a bunch of addresses like house numbers and streets, the DNS is a master list that keeps track of what addresses belong to who at any given momment, when that goes down theres no more yellowbook, the computer looks for the company called yahoo, it has no reference for its address so it has no idea where to look and the web comes crashing down heh. they have a few servers, so a few road maps still exist, but its full of holes.

buuut it seems to be back up now as of 3:45pm so...

if the "DNS servers" went down (which there are 13 main ones btw..) they are each redundant and they would just point to each other in case of error. Whoever told you that was bull****ting you.

i was having trouble with Hotmail and Ebay, but now both are working.

yay! the internet! yay!

This was the response I got from a very trusted source the last time Comcast had a similar situation. I did not verify this one, but the user problems seemed similar.
