atdn.net issues
by Randy Carpenter 23 Feb '11

23 Feb '11

Anyone know who to contact for issues with atdn.net? Their website is not exactly a well of information. All connections from my network to anything at atdn (AOL, etc.) are dying at atdn's edge. Traceroutes go out through xo.net. I have verified that both of my upstream providers can get there fine (via the same path), so it appears to be a problem specifically with our net blocks (74.115.180.0/22 and 74.219.82.0/24) or ASN (15088) If anyone has any visibility from the other side of atdn.net, and can give me any info, I would appreciate it. thanks, -Randy

Internet Issues in Europe Tonight?
by Ryan Gelobter 23 Feb '11

23 Feb '11

Does anyone have some detailed information about the internet issues going on in Sweden and other parts of Europe right now? I've read some reports about a large Telia outage in Sweden indicating a fault somewhere in Frankfurt or London as the cause. http://www.aftonbladet.se/nyheter/article8609308.ab http://www.dn.se/nyheter/sverige/stort-internetfel-i-europa

[OT] Internet connectivity options in Afghanistan?
by Janet Sullivan 22 Feb '11

22 Feb '11

I'm looking for cheap/slow internet connectivity options in Kabul, Jalalabad, and Herat. The connections will be used by AFCECO orphanages, so speed isn't as much of an issue as cost. I'm guessing that satellite might be the only game in town, but if any of you fine folks know of connectivity options, I'd appreciate an email.

BGP Failover Question
by Chris Wallace 22 Feb '11

22 Feb '11

I am looking for some help with an issue we recently had with one of our BGP peers recently. I currently have two DIA providers each terminated into their own edge router and I am doing iBGP to exchange routes between the two edge routers. Last week Provider A made a policy change "somewhere" in their network in the middle of the day causing traffic to stop routing. Of course this connection happens to be the preferred route for the majority of our inbound and outbound traffic. I never saw our physical link go down and never saw our peer drop therefore BGP did not stop advertising routes, this caused most of our customers traffic to go nowhere. In order to fix the issue I had to manually shutdown the peer till Provider A confirmed the change they made had been reverted. This isn't the first time we have seen this issue with our various providers, how can I prevent issues like this from happening in the future? ---Chris

Is there a process to revoke netblocks from entities which deny ownership? http://www.db.ripe.net/whois?searchtext=77.223.129.43 The admin-c, tech-c deny any responsibility for this netblock. -Dan

Deal NANOG, Does anyone know where I can get real/raw BGP traffic, maybe in pcap format? I just need maybe a few days of raw data for an inline analysis tool I am developing. Thank you, Javier

Re: Traffic to 5/8 and 37/8 - stats on RIPE Labs

Hi Oleg, You are correct. We got our default values mixed up. We will correct this on the blog post.

Graph Utils (Open-Source)
by Max Pierson 21 Feb '11

21 Feb '11

Hi List, Anyone out there using something other than rrdtool for creating graphs?? I have a project that will need a trend taken, and unfortunately rrdtool doesn't fit the bill. All of the scripting, data collection, database archival, etc will be custom written or is already done (with some hacks of course :). So really what i'm looking for is something along the lines of GNUplot. Has anyone used it before and would like to share experiences?? Seems like it will be able to my plot data accordingly, but wanted to see if there were any other popular tools I've yet to come across. (Open-Source only please) TIA, M
