>> we nearly lost all of our data since our last backup (it was only a few days, but an important few)
Daily backups !
general recomendations:
quality server (Dell/HP/etc) NO ide drives! SCSI in software raid5 minimum software install (e.g. no compilers)
get second 'devel' server to test/compile software before using on production server If it is not broken, don't fix it. as in screw with the devel server.
Realize you are in over your head and use an existing datacenter.
They have already done all the things you have done, all the things you are realizing you forgot, and all the things you will not find out about until everything fails.
You can now move on with you core business, whatever it may be.
quick options 1: use two providers
you get to keep your address
you have redundancy
2: hire someone that has done this before
long solution: get your own address from arin or suitable authority. with 90 companies connected, getting a/20,/19, or/18 should not be a problem
bring up second connection. establish BGP sessions with both providors announcing all (old and new) ip addresses.
plan on transitioning a few customers per day. I imagine most of your customers are 9-5ers. They are easy. Save the more critical ones to last as you'll have had a lot of practice.
Using DHCP on their side helps
Co-ordinate with the companies IT person. You update the routers/routes, and they update the DHCP server. Easiest done as they leave for the day.
do not do NAT in the routers. It will kill your performance.
The whole transition could take up to two or three months. Don't get in a hurry. Do it right the first time.
Setup DNS servers on both old and new ip address blocks.
Consider keeping the old connection (maybe at a lower bandwidth) for redundancy. or kill old provider connection.
If you state that all of you are: a) getting your own cubicle b) sharing a cubical c) getting you own office d) getting a shared office
most likely nobody will like the decesion.
If instead you gather everyone together and say, "Hey, since we are moving we have a choice of how we arange the office. What would you like?"
Letting the developers/sysadmin/etc people have more control over their environment will generate a better atmosphere overall. Which leads to better productivity. I forgot where this came from, but it isn't my original idea.
If they want a 'bull pit', then give 'em a bull pit. If they want individual cubicals, then give 'em that. Maybe a combination, some one way, others the other.

If there is a jack, there is a phone and ethernet both. run all the cat5 to a patch panel. Running cable is fun... for an hour or so. Let the expert do it and save yourself some grief.
Get O'reilly's "Linux in a netshell" book. This is exactly why I got my first one, and my second one (3rd edition).
There is a section on "linux commands", along with smaller sections on bash,csh/tcsh. A section on emacs and a section on vi. Plus sections on sed and awk.
It is a very nice "quick reference manual" for those times when you need to know what the '-M' option to rdist does.
Dell poweredge servers can do this. You initally need a keyboard and monitor to change a BIOS setting to use the serial port. After that you can manage it from a console ala cisco gear or sparc. You'll need to setup lilo to tell it to use the serial port and also setup a getty on the serial port.
This is _exactly_ what you want. and it has 3, that is three, built in eithernet ports.

If you had to use --force and --nodeps, you did something wrong.
To update glibc and the kernel this would be the procedure:
download the rpms
read some release notes.
rpm -Uvh glibc-common-... glibc-devel-... glibc-2...i686.rpm
(if you are on a PII or up)
For the kernel itself: NEVER do a --freshen or --upgrade

Hello...
I have asked several transit providers here in the USA about providing IPv6. The answer, "Nobody is asking for it".
The Tier 1 and Tier 2 ISPs will not provide IPv6 until there is a market for it.
The solution? Ask for native IPv6 (not tunnels) from your ISP. If you switch ISPs ask for IPv6 in the RFP.
Realize you are in over your head and use an existing datacenter.
They have already done all the things you have done, all the things you are realizing you forgot, and all the things you will not find out about until everything fails.
You can now move on with you core business, whatever it may be.

If you had to use --force and --nodeps, you did something wrong.

(if you are on a PII or up)
For the kernel itself: NEVER do a --freshen or --upgrade
rpm -Fvh kernel-utils.. kernel-source... kernel-pcmcia... kernel-headers...
rpm -ivh kernel-2.4.1-0.1.9.i686.rpm
This way you have two kernels installed! "just in case (tm)"
If you have scsi, make your initrd
update lilo and run 'lilo'
> and did 'for i in *rpm; do rpm -Fvh $i; done;'
Try rpm -Fvh *rpm .
That will upgrade all of them in the proper order at the same time.
