Reading/posting on usenet rbm and rbt
Hi folks,
Anyone understand well how the usenet works? I look at it in three ways and can't figure out how the lag time works between when a new subject has been posted and when it appears in different forums. More specifically, I use outlook express with a news server, cyclingforums and google. When I post using Outlook Express, I can't see it for hours, if not a whole day, on the other two forums. I also know google has a delay of minutes or sometimes hours compared to cyclingforums. Can anyone shed some light on this? While you're at it, where is all the info posted stored? Some University server? Joshua |

(You don't have to use your ISP's). I'll post this and see how long it takes with mine..... Back in a tick. ~PB |

Go to:
http://groups.google.com/groups?hl=e...p=rec.bicycles and use Google for all your posts and replies. I quit using my ISP's news server because it would get too delete happy. There is almost time delay. |

I look at it in three ways and can't figure out how the lag time works between when a new subject has been posted and when it appears in different forums. That's because there are numerous factors which may speed or delay propagation, and not all of them are visible to you. More specifically, I use outlook express with a news server, cyclingforums and google. When I post using Outlook Express, I can't see it for hours, if not a whole day, on the other two forums. I also know google has a delay of minutes or sometimes hours compared to cyclingforums. Can anyone shed some light on this? While you're at it, where is all the info posted stored? Some University server? Oboy. Okay, first, there is no single central repository for Usenet traffic, and indeed, there is no physical "thing" called Usenet; the articles are just bits of information that are traded around between machines on the Internet and off of it, and the server processes that store, sort, catalog, fetch and forward those articles are each autonomous and often disparate packages that run on the machines where their administrators have placed them. Each news server maintains its own cache of articles, grabbing fresh ones from servers that it talks to, and making available those that it has stored or which it has received from users, according to the unique setiings that its administrator has configured. If you look at the Path: line of a Usenet header, you'll see how many hops the article in question made before it got to the server you use. Each server in that path represents a propagation delay of anywhere from milliseconds to hours. Two articles posted at identical times on two different servers, even though the servers might be in close physical proximity, could have propagation times to a third server that could vary by a full day. So, to answer what I believe is your unstated but central question, the reason it seems random and unpredictable is that it *is* random and unpredictable to a large extent. -- My email address is antispammed; pull WEEDS if replying via e-mail.

I find the path from your server (Earthlink) to mine (Sonic) a classic of Usenet. No doubt that path is also variable. Path: typhoon.sonic.net! feed.news.sonic.net! HSNX.atgi.net! news-han1.dfn.de! news-lei1.dfn.lei1.dfn.de! news1.uni-leipzig.de! fu-berlin.de! uni-berlin.de! individual.net! From: Werehatrack So, to answer what I believe is your unstated but central question, the reason it seems random and unpredictable is that it *is* random and unpredictable to a large extent. I don't know why it chose to go via Germany but that may be because traffic is low right now. I also fin interesting that Earthlink does not appear on the chain, but then you may be posting from some other place. Sonic is a great and fast connection for me and it supports tin (a smart threaded news reader) with emacs that is designed to format postings to newsgroups. |
