Notifying customers of upstream modifications
by Andy Susag 29 Dec '11

29 Dec '11

Hi All, Just a quick question for those of you running ISPs with BGP downstreams. If you add or remove an upstream provider to your network, do you provide notification to your downstream customers? Likely, it would cause a shift in their traffic. If they are peering with multiple ISPs themselves, they may see a traffic flux. I know for a fact that our upstreams do not notify us of events so we tend to not send out these sort of notifications. Just wonder what everyone else does or if anyone happens to know "best practice" Thanks, Andy

Merry Chrismafestihanukwanzstice to everyone reading NANOG on this holiday weekend. And now, for some On Topic technical content, I bring you RFC 1882 (it's an RFC, by definition it must have some relevant content for network operators :-): http://www.ietf.org/rfc/rfc1882.txt Network Working Group B. Hancock Request for Comments: 1882 Network-1 Software and Technology, Inc. Category: Informational December 1995 The 12-Days of Technology Before Christmas Status of this Memo This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Discussion On the first day of Christmas, technology gave to me: A database with a broken b-tree (what the hell is a b-tree anyway?) On the second day of Christmas, technology gave to me: Two transceiver failures (CRC errors? Collisions? What is going on?) And a database with a broken b-tree (Rebuild WHAT? It's a 10GB database!) On the third day of Christmas, technology gave to me: Three French users (who, of course, think they know everything) Two transceiver failures (which are now spewing packets all over the net) And a database with a broken b-tree (Backup? What backup?) On the fourth day of Christmas, technology gave to me: Four calls for support (playing the same Christmas song over and over) Three French users (Why do they like to argue so much over trivial things?) Two transceiver failures (How the hell do I know which ones they are?) And a database with a broken b-tree (Pointer error? What's a pointer error?) Hancock Informational [Page 1] RFC 1882 12-Days of Technology Before Christmas December 1995 On the fifth day of Christmas, technology gave to me: Five golden SCSI contacts (Of course they're better than silver!) Four support calls (Ever notice how time stands still when on hold? Three French users (No, we don't have footpedals on PC's. Why do you ask?) Two transceiver failures (If I knew which ones were bad, I would know which ones to fix!) And a database with a broken b-tree (Not till next week? Are you nuts?!?!) On the sixth day of Christmas, technology gave to me: Six games a-playing (On the production network, of course!) Five golden SCSI contacts (What do you mean "not terminated!") Four support calls (No, don't transfer me again - do you HEAR? Damn!) Three French users (No, you cannot scan in by putting the page to the screen...) Two transceiver failures (I can't look at the LEDs - they're in the ceiling!) And a database with a broken b-tree (Norway? That's where this was written?) On the seventh day of Christmas, technology gave to me: Seven license failures (Expired? When?) Six games a-playing (Please stop tying up the PBX to talk to each other!) Five golden SCSI contacts (What do you mean I need "wide" SCSI?) Four support calls (At least the Muzak is different this time...) Three French Users (Well, monsieur, there really isn't an "any" key, but...) Two transceiver failures (SQE? What is that? If I knew I would set it myself!) And a database with a broken b-tree (No, I really need to talk to Lars - NOW!) Hancock Informational [Page 2] RFC 1882 12-Days of Technology Before Christmas December 1995 On the eighth day of Christmas, technology gave to me: Eight MODEMs dialing (Who bought these? They're a security violation!) Seven license failures (How many WEEKS to get a license?) Six games a-playing (What do you mean one pixel per packet on updates?!?) Five golden SCSI contacts (Fast SCSI? It's supposed to be fast, isn't it?) Four support calls (I already told them that! Don't transfer me back - DAMN!) Three French users (No, CTL-ALT-DEL is not the proper way to end a program) Two transceiver failures (What do you mean "babbling transceiver"?) And a database with a broken b-tree (Does anyone speak English in Oslo?) On the ninth day of Christmas, technology gave to me: Nine lady executives with attitude (She said do WHAT with the servers?) Eight MODEMs dialing (You've been downloading WHAT?) Seven license failures (We sent the P.O. two months ago!) Six games a-playing (HOW many people are doing this to the network?) Five golden SCSI contacts (What do you mean two have the same ID?) Four support calls (No, I am not at the console - I tried that already.) Three French users (No, only one floppy fits at a time? Why do you ask?) Two transceiver failures (Spare? What spare?) And a database with a broken b-tree (No, I am trying to find Lars! L-A-R-S!) Hancock Informational [Page 3] RFC 1882 12-Days of Technology Before Christmas December 1995 On the tenth day of Christmas, technology gave to me: Ten SNMP alerts flashing (What is that Godawful beeping?) Nine lady executives with attitude (No, it used to be a mens room? Why?) Eight MODEMs dialing (What Internet provider? We don't allow Internet here!) Seven license failures (SPA? Why are they calling us?) Six games a-playing (No, you don't need a graphics accelerator for Lotus! ) Five golden SCSI contacts (You mean I need ANOTHER cable?) Four support calls (No, I never needed an account number before...) Three French users (When the PC sounds like a cat, it's a head crash!) Two transceiver failures (Power connection? What power connection?) And a database with a broken b-tree (Restore what index pointers?) On the eleventh day of Christmas, technology gave to me: Eleven boards a-frying (What is that terrible smell?) Ten SNMP alerts flashing (What's a MIB, anyway? What's an extension?) Nine lady executives with attitude (Mauve? Our computer room tiles in mauve?) Eight MODEMs dialing (What do you mean you let your roommate dial-in?)

Well Lookie Here, Barracuda Networks tries to get me to fall into their trap again...
by John Palmer (NANOG Acct) 24 Dec '11

24 Dec '11

Well look what was in my in-box this morning! Looks like Barracuda Networks is sending out spam again. Maybe word is getting around about their less that value-full renewal policy. Could it be that people are starting to resent being taken advantage of?? See my response below their message. Seems like they don't remember that I was a fish they already hooked and fleeced. --- SPAM from Barracuda ---- Howdy, Just following up with you about a project you were working on with Barracuda Networks. Checking in to see how things are going for you. Have you had network changes recently or a issue pop up that we can help solve? Let me know if you would like a solution guide for reference. Happy December, --- Message sent in response to the sales droid message from Barracuda --- Hi Jaz, No, things are about the same. I see by your website that you haven't changed a bit and continue to think that it is an honest business practice to charge people for a service and then not to deliver it. When I renew my Barracuda Engergize subscription, THE RENEWAL SHOULD BE FROM THE DATE THAT I RENEW, NOT THE ANNIVERSARY DATE! Many small businesses have cash flow challenges and cannot renew their subscription right at the expirartion date. Where does that leave them? If they have to delay their renewal by three or four months, they then get greeted by your company charging them for an entire year of service when they only actually get 8 or 9 months, since the renewal goes from the anniversary date instead of the anniversary date being reset to the actual date of renewal. As it stands right now, If we were to renew our Energize subscription, We'd have to pay for FIVE YEARS of service but would only get THREE years. If that isn't a rip-off, I don't know what is. I think this is dishonest business practice. I will no longer give money to what I view as a crooked company such as yours. I have posted about this corrupt practice on my blog (http://www.john-palmer.net/wordpress/?p=46) and on facebook. Think I'll "bump" each of those postings to refresh them in the search engines so that people continue to be informed of this practice so that they won't fall into the trap of doing business with your company as we did. Perhaps for your collective New Year's resolution at Barracuda Networks, you can all resolve to operate your business in an honest fashion and provide FAIR value with FAIR business practices in 2012, both of which, in my opinion, you are severly lacking. Maybe then, PERHAPS, we may look at doing further business with you.
