[UCIMC-Tech] bikeproject.org file edits not appearing on on site

Hi,
Looks like something changed in DNS in the past three days or so, and thebikeproject.org is again being served by fixx0, so is displaying a weeks-old version I can't edit...
From dig:
thebikeproject.org. 300 IN A 75.145.177.76
fixx0.chambana.net. 10800 IN A 75.145.177.76
imc.naf.chambana.net. 10800 IN A 209.66.96.72
Could someone change things back so the site is served by imc.naf.chambana.net ?
Details:
When I browsed to thebikeproject.org just now, I was served the weeks-old site version that was on fixx0. Server logs on imc.naf are not showing my browser accesses. From the look of the logs, the changeover happened in the last few days; I see normal, non-crawler. accesses up through Jan. 22, but only web-crawlers (which cache IP's, unlike humans?) after that.
Thanks for any help.
Cheers,
Barry

Checking the list archives, looks like my recent mails to IMC- Tech have been (silently!) bouncing; I mailed then from my gmail account, not my UIUC account. I'll remember to send from an address that is actually a member of the list in future. But shouldn't I get a 'your message awaits moderator approval' mail if I make this mistake?

I'm typing this without limited access to the machines involved, and just a short look around, so forgive me if I get too far off here, especially on your network-attached filesystem approach. Apologies for the following combination of my own ignorance and possible reviewing of obvious things...

I see root dir (/) for imc.naf is rasputin's /naf , which is a little different from configurations I'm used to, so I may be off on the basic concept here...

Plus, if any other machine is running apache2 or serving needed files and I haven't realized it, similarly restart those too. Uptime on imc.naf is 68 days. Experience from NFS: Sometimes, with a stale NFS handle, and maybe with other confusion based on moved mount points, only solution is to restart the machine. (I suppose restarting NFS should work, but if if you going to go that far anyway, might as well restart or power cycle.)

In all of above approaches I'd try to access thebikeproject.org web site while the targeted machine/service/file system was unavailable. That is, when apache2 is not running on imc.naf, for the few seconds when imc.naf.chambana.net was powered down, or when all apache2 processes are verified killed, try to browse thebikeproject.org, to make sure some other server independent of imc.naf isn'y somehow serving the page.

One responds to web queries with week-old pages, and is not logging to access and error logs. Another seems to respond to one or two accesses a day and is logging to access and error logs (there should be hundreds of log entries, including the handful of test accesses I've been generating each day, but there are only two or so each day in

This would be less confusing if there were _no_ log entries each day in access/error logs, but each day a couple appear -- and they are not the test accesses that I make. Could this point to some recently switched-around IP numbers / DNS server changes?
