Weird Problem

[CKH]

I have a cable connection and 3 computers, all with different IP's connected to the internet. All of a sudden, the one computer that I use to connect to the internet, stopped connecting to 3 sites.

2 of the sites are mine and hosted on Powweb. The third site I tried was www.powweb.com.

The other 2 computers connect with no problem, as you can see as I'm posting a message here. The other computer doesn't seem to have any problem connecting to any other sites. I also noted that it was having problems connecting to my email server, 2 different mysql servers (01 & 04) and can't connect via FTP either. (socket error 10060).

It's almost like powweb banned my IP??

I can connect to mysql on another host, ftp, http, email, etc, only not with Powweb based servers and only with the one computer.

Any suggestions??

where do your traceroutes stop? we don't filter individual ip's. we filter netblocks so assuming cox's cable network is set up like the rest of the cable providers all your machines are on the same netblock. and i don't have a filter for your netblock. if you could post a traceroute it would be helpful.

I'm going to have to type it in by hand but:

1 10.32.128.1
2 68.2.1.133
3 68.2.14.9
4 68.1.0.164
5 68.1.0.88
6 68.1.0.95
7 198.32.175.14
8 129.250.3.84
9 129.250..5.49
10 129.250.5.96
11 129.250.29.115
12 204.0.193.7
13 216.52.255.95

14-29 show no response. Timings are 0ms to 51ms with an average of about 30.

Additional traceroutes got a no response from 13 on.

our service provider ran into a cisco bug on one of their switches serving our facility. it basically generated corrupted routing tables. i believe the issue has been resolved now.

Cisco problem today, is it still affecting us sporadically?

internap says its resolved.

I got it working by going to bed, getting some sleep and coming back to the computer.

Amazing what problems a little sleep can fix.

Thanks for the info...

Its resolved. I called them when this happened around 11 PM last night and talked to the support which was a mess, but finally with my ISP and Several phone calls I learned this was not powwebs problem but another companies problem. My site was down (for me atlest) from 11 PM - 4 AM this morning which was crazy.

How it basically works is different ISP's use Different DNS Servers. Like me I have RR internet service, and I could not access my site, however my friend down the street has the same setup as I did and he could. Its because each set of DNS Servers use different routing servers. I learned this when I called up Tech Support last night a 1 AM for my ISP who then answered all my questions, which explains why some people using dial up and high speed could reach my site and others could not.

well not really. everyone was going through that switch but it was only affecting some people. it was a corrupt routing table on our service providers switch immediately in front of us. dns and route propagation are two completely different entities and neither of them overlap or are dependant on eachother. all dns does is translate names into numbers not how to get there, that's where routing comes in.
