Colo site selection
by Rich Braun 24 May '00

24 May '00

One of the more-vexing aspects of network planning and deployment is picking out space for facilities. The good ones are taken (i.e. no available rack space); many are not carrier neutral (I have to go through provisioning purgatory to add or repair a circuit); and now a new phenomenon seems to be spreading--big empty data centers getting built out at a frenetic pace, at least here in Boston, but with no one important to whom I can connect. Beancounters also make life interesting--by the time they approve the deal at $X per square foot, the vendor turns around and insists on $(X+Y) per square foot. Then the beancounter asks, with a perfectly straight face, why the price is 3x higher in Boston (or wherever) than the deal he just approved in Atlanta...ugh. I'm seeking to either commiserate with others who have to deal with this site-selection hell, or to find out some useful sources of research and contact info about useful sites whose prices aren't outrageous. My affiliation is Primus Telecomm, and this question applies to both USA and non-USA locations. -rich

UUNet?
by Jeff Wheat 24 May '00

Does anyone know what happened on Monday? Seems like it has been hushed up as I can find no information about it anywhere. Contacting UUNet results in them telling us that their legal department is working on a press release... Thanks, Jeff

That pesky AS path corruption bug...
by Blaine Christian 24 May '00

24 May '00

Hello all, After observing a recent issue regarding a router that sent corrupted AS path (all names are witheld to protect the guilty). I took a look at the path information that was being received and have a possible solution. Since the corrupted AS-path does not include the AS that the route is coming from (at least in the corruption that I saw) it seems to me that a simple solution for all is to filter on AS i.e. only allow routes that have the AS of your EBGP neighbor prepended to them. I realize this does not cover all cases of wacky AS corruption problems but it may fix some of them. I would suggest that those of you running mixed vendor EBGP (again names witheld) should implement a version of this strategy for your own self protection. It can certainly be implemented as part of an overall customer access functionality. This may be obvious to some of you but I do not believe that everyone is at this level yet. Of course the tirade part of this email is for all vendors involved in this travesty. If you do not understand or dislike a route that you have received don't just CRASH. Anyone ever thought of checking the route and throwing it out with an error message if you don't like it? I, of course, have heard and seen that several vendors have fixed this in the more recent releases. This type of bug is something that everyone who writes software has to deal with. If you raise an exception for bad input it is bad form to crash or reset your application. BTW, I am sure all have heard this argument before. I just wanted to get this topic renewed. Regards, Blaine

Cryptography is good for detecting alterations, not if the information was correct in the first place.

OT List Questions
by Dennis L. Shreve 24 May '00

24 May '00

Pardon the OT bandwitdh. I'm new to the nanog list and have a couple quick questions: Is this a low volume list? I am not receiving any posts. Should I not get copies of all messages to the list including my own? Where can I get instructions on list usage and options? Joe was kind enough to reply to my test (which I never saw cross the list), but the reply was to me directly, instead of to the list so I cannot tell if I'm receiving from the list? Sorry for the intrusion, your assistance is appreciated!! Thanks, Dennis ... ------------------> > -----Original Message----- > From: Joe St Sauver [mailto:JOE@OREGON.UOREGON.EDU] > Sent: Tuesday, May 23, 2000 6:55 PM > To: d_shreve(a)nvbell.net > Subject: Re: test > > > It works. > > Joe
