Anyone else affected by AT&T server grab? - 8/29/2007 10:04:13
As of yesterday at 10AM my website became unavailable for viewing by me.
www.nrgsaver.com
My web host tells me they can see it and so can most of the world. That AT&T has blocked a group of servers and that the one I am on in Texas must be one of them. However, my daughter in Chicago can't access my site either.
Has anyone else heard of this or been affected by it.
Does anyone know where I could go to get more information on this.
Calling AT&T would be like looking for a needle in a haystack. I have googeled the AT&T issue without results.

I can access it. You might try MegaProxy as well to see if that works.
Does your daughter use the same ISP?

I can see it. Doesn't look like anything unusual

RE: Anyone else affected by AT&T server grab? - 8/29/2007 15:56:01
My site is now back up after 12 hours of being down.
We tried MegaProxy last night as well as several others and received a message "proxy service received an invalid response from upstream server".
My daughter is on an entirely different ISP from 1400 miles away.
Here is what I was told by a superviser at my hosting company.
AT&T decided a block of servers belonged to them in their recent acquistion. So they blocked those servers and my own ISP must have been in that block. Therefore I could not connect.
I was having a lot of problems with that explanation for several reasons that didn't make sense to me.
1. Why was I able to access other web sites but not my own?
2. What were the chances that my daughter and I would both be in that block that AT&T supposedly blocked given the distance and ISP difference?
3. If the problem was at my local end and not at the web host then why in any given random routing would I not be able to access my site at least once. In other words, it would not be possible to travel a differnt path twice and hit a blocked server both times.
I'm not the smartest in the world when it comes to behind the scences stuff on the internet but something just didn't add up.
However, I will say that my web host seemed sincere and honest about it, and tried very hard to answer my questions.
I would think this would have been pretty big news and I can't figure out why there was nothing on the web about it. My host said there was nothing they could do, as it didn't involve them directly but that negotations were going on at a much higher level of the internet to get AT&T to unblock the servers.
Who knows!

Do you have email attached to that domain? Could you get that?
I have heard of some ISPs deleting their DNS cache. I came across this a few times when I was offering hosting.
It would have been interesting to check to see if you could have accessed other sites on that server or data center (DC).
I think that traffic is directed to a few data centers... (I could tell you how a LinkPoint transaction goes, but not the Internet.) And there is one DC in Los Angeles and one on the East Coast I think. I remember a few articles about charging some users for Internet access but I did not pay too much attention to that one either

I don't think it had anything to do with AT&T. I do believe that your ISP was just plainly down. Sometimes things like that do happen. Also 12 hours would be a long time.

I would have thought so too except I was able to go on the internet and go to other sites. I was able to check my site thru Megaproxy for instance.

Yes I have email attached and yes I did receive the email while my site was down.

I was able to access their site. However, I don't know if it was on the same server as mine because they have lots of them. But most of the techs were aware of the problem because they said they had gotten lots of calls from other customers. They did tell me that there are only a few of the big guys holding all the main router servers and AT&T had only blocked a set of theirs that they had in question.

If you were able to check it through a proxy, that would mean your ISP had problems. Next time if it happens, do a tracert though to your domain and then to your email server. They should be going to the same DC at least.

Anything new on this one?
I, and several of my members, haven't been able to access our forum (hosted through WOWBB) since Friday. And, by not access, I mean the browser times out when attempting to access the website.
According to them:quote:
1. ALL of our servers ARE online.
2. We have rebooted the servers.
3. We have rebooted the domain routing services.
4. We have verified that ALL of the sites reporting "outages" ARE working and online by having friends of WowBB in different areas of the world access them.
5. The issue appears to be isolated to a ROUTING PROBLEM on ONE or MORE of the MAIN servers that "run" the internet.
The issue lies in equipment that WOWBB does not own, NOR have access to.
The odd things being,
1) I have still been receiving email through the website.
2) The rest of our members all over the road are continuing to have no problems at all accessing the site.
3) It is only this one website that we have any trouble accessing.
Thoughts?
News?

What does a tracert show? What about the proxy site I mentioned?

This was exactly what I experienced (the same symptoms) and exactly what my web host told me, except they seemed to know AT&T was causing it.
What I can't figure out is why there isn't more news on this since this is the same type of thing that caused the SEC to dismantle AT&T in the 80's.
I don't understand why you are still down though, since I assumed once my site got back up that the problem had been resolved. You might want to check with your web host what they have heard about this, if anything.

When I use MegaProxy, I can pull up the site no problem. And I (and some other members) still can't pull up the site, if we try at it directly.

Update:
LiquidWeb recieved the email from AT&T and cannot find anything along the lines of what AT&T claims.
It is my personal belief that the issue is NOT with liquid web because all of the TraceRTs we have recieved from customer.. NONE of them terminate at liquid web.
Normally if LiquidWeb was blocking an IP address, your last "HOP" on your TraceRT would be their first server and then it would "TimeOut". In all of the trace routes we have gotten, the last server is NOT a liquid web server.
Example A
(Server Being Blocked by AT&T)
Tracing route to mywowbb5.com [69.16.220.48]
over a maximum of 30 hops:
1 2 ms 1 ms 1 ms Router [192.168.1.254]
2 17 ms 16 ms 16 ms adsl-76-217-127-254.dsl.emhril.sbcglobal.net [76
.217.127.254]
3 14 ms 15 ms 15 ms dist2-vlan60.emhril.ameritech.net [68.22.72.131]
4 17 ms 15 ms 15 ms bb2-g10-0.emhril.ameritech.net [151.164.43.84]
5 16 ms 15 ms 16 ms 151.164.94.41
6 gar8.cgcil.ip.att.net [12.122.79.89] reports: Destination host unreachable
.
Trace complete.
Notice how at hop 6 it Terminates at an att.net server?
Now we do one that makes to liquid web.
Example B
(Trace Goes through to final destination)
Tracing route to mywowbb3.com [209.59.135.149]
over a maximum of 30 hops:
1 4 ms 1 ms 1 ms Router [192.168.1.254]
2 17 ms 16 ms 16 ms adsl-76-217-127-254.dsl.emhril.sbcglobal.net[76.217.127.254]
3 15 ms 15 ms 15 ms dist1-vlan60.emhril.ameritech.net [68.22.72.130]
4 17 ms 16 ms 15 ms bb1-g0-0.emhril.ameritech.net [151.164.43.82]
5 15 ms 15 ms 15 ms ex2-p9-0.eqchil.sbcglobal.net [151.164.42.141]
6 16 ms 17 ms 15 ms gar8.cgcil.ip.att.net [12.122.79.89]
7 23 ms 23 ms 23 ms tbr2.cgcil.ip.att.net [12.122.99.66]
8 23 ms 23 ms 23 ms tbr2.dtrmi.ip.att.net [12.122.10.133]
9 21 ms 21 ms 21 ms gar3.dtrmi.ip.att.net [12.123.139.141]
10 40 ms 41 ms 42 ms lw-core2-ge2.rtr.liquidweb.com [209.59.157.34]
11 42 ms 41 ms 41 ms lw-dc1-dist2-ge2.rtr.liquidweb.com [209.59.157.18]
12 41 ms 41 ms 41 ms host.mywowbb3.com [209.59.135.149]
Trace complete.
Notice how all of the hops up to hop 6 in BOTH examples ARE THE SAME.
Notice how the hops AFTER step 6 in the GOOD example there are still THREE servers that are left to pass through BEFORE you reach liquid web.
Notice those 3 servers are ALL AT&T servers.
This is STRONG evidence that it is an AT&T issue. Something is wrong with the 12.122 cluster.
