We're looking at using Comcast's (business) transit and private ethernet services at several client locations and I wanted to see what experiences others have had regarding this. Off-list replies are preferred. Thanks, -brandon -- Brandon Galbraith Mobile: 630.400.6992

rj21/centronics cable mounting
by Ingo Flaschberger 07 Jan '10

07 Jan '10

Hi, I'm searching "something", to secure mount/connect a rj21 cable to a device. I have a angled plug like this: http://commons.wikimedia.org/wiki/File:RJ21-female-connector.jpg It can only be screwed to the device at the top side, and is "loose" at the down side. I have seen a type of "knop" at the down side and also that a "hook-and-loop fastener" is used over the whole plug. (http://www.retrevo.com/r/23018bh245/18/ADSL+RJ21+Pinouts/) Any ideas where to get this or any other ideas how to get a good connection? (retro-fit). I know, "straight" rj21 plugs would also solve the problem. Kind regards, ingo flaschberger geschaeftsleitung ____________________________________ crossip communications gmbh A-1020 Wien, Sebastian Kneipp Gasse 1 Tel: +43-1-7261522-0 Fax: +43-1-726 15 22-111 www.crossip.net _______________________________________________________________________________ crossip communications gmbh

Don't think anyone has mentioned this yet, so I will.... All this debate over the pros and cons of firewalls brings the words "Jericho Forum" to mind.....and their "principles for de-perimeterization (perimeter erosion)" http://www.opengroup.org/jericho/ Just my 2<insert_currency> worth !

Re: Data Centre - Advice? (Shenzhen, China)
by Scott E. MacKenzie 06 Jan '10

Wow, missed this one reply. Sorry Benjamin. 1) Define "tier one". Let's go with this definition: http://en.wikipedia.org/wiki/Tier_1_network I hope the definition helps? ________________________________________________________ NTT got some IDC in China (Beijing, Guangzhou, Hong Kong, Shanghai, Suzhou), but not in Shenzhen. I noticed that the NTT sites are look owned by third parties. Can anyone confirm this? Chinanetcenter would be there: http://www.chinanetcenter.com/wangsu/english/co/Shenzhen_Banxuegang_IDC.htm Remember Hong Kong is well served in Datacenters and upstream providers, and well, just next to Shenzhen. Thank you, for the feedback. We will be looking at chinanetcenter next week and I will let you know my thoughts. Hong Kong is not going to work as our clients are in China and the network delay (latency) to HK is excruciatingly painful. It is like sending a packet around the globe from Shenzhen to HK. I don't know why, but I have my suspicions. Anywhere inside the PRC the network is blazing fast from point to point. _________________________________________________________ 2) Define "technology foot print" =) Couldn't respecting RFC be a foot print already? No joke, please give more details about your "technology". Servers, switches, routers, firewalls, load balancers, etc... When serving your clients inside the PRC from outside the PRC, does anyone have any feedback, thoughts, comments, or suggestions surrounding placement of gear - as in inside or outside the PRC. Thus far it looks not good from HK or Taiwan. Our concern is delivering the best possible experience to our clients using the services we offer. (SaaS, MashApps, Etc.) We need low latency, moderate bandwidth, and 100% uptime - or very close to it... Scott Best, Benjamin Le 10/12/2009 05:57, Scott E.
