Email hosting
by Dan Lockwood 09 Nov '01

09 Nov '01

Does anyone have any experincing in quantifying, in terms of dollars, what I should expect to pay for outsourcing an email system. I'm looking at ~1000 mailboxes and am primarily interested in POP3. Any suggestions? Dan Lockwood Office: 530-225-0261 Mobile: 530-949-1302 Pager: 888-578-7218 CompTIA Network+ Certified Microsoft Certified Professional + Internet Cisco Certified Network Associate

Is there another poison BGP route floating around tonight? I'm seeing odd routes across several providers, and routes are coming and going.

I don't know. route-views.oregon-ix.net as measured by http://kahuna.telstra.net//bgp2/as6447/ shows a big drop in routes on the 2 day report. But none of the other BGP tables show any unusual changes. www.internetpulse.com indicated problems with their San Francisco beacon. None of the other public Internet measurement sites showed problems. I had intermitent problems getting from the west coast to the east coast for 30 minutes. Everything is back to normal now.

IP database ideas
by Charles Sprickman 08 Nov '01

08 Nov '01

Hello all, I just discovered Postgres (after having used MySQL for some time), and it has some IP datatypes. I'm looking to stuff all of our IP allocations into a db for easier allocation/tracking, and I'm just thrilled to see that I can store IPs/networks natively. Before I get too far into this, are there any pre-existing packages out there to help manage IP allocation? Does anyone have anything homegrown, and would you be willing to share some pieces, even just a schema, or advice? I don't want to dive in and find that I've laid everything out poorly and painted myself into a corner...

Level3
by Joel Baker 08 Nov '01

08 Nov '01

Level3 is having significant issues right now, due to routers in Dallas. They're working on it, no reported ETA yet. Routing is bad enough that we turned down BGP to them until it stabilizes. Their customer service seems to be operational and aware of the issues, if a bit overwhelmed by volume (unsuprisingly). -- *************************************************************************** Joel Baker System Administrator - lightbearer.com lucifer(a)lightbearer.com http://users.lightbearer.com/lucifer/

CNN video streaming
by Hank Nussbacher 07 Nov '01

Recently we have been experiencing weird problems when accessing the CNN video content. Via certain ISPs only Real works, via others only WMP works, with yet others - neither works. Anyone have the same problems? -Hank
