Heads up! Moving the site to a different server
May 8th, 2007 at 6:51pm
 
heads up.

my host will be moving the server soon. not sure exactly when.

going to a server with upgraded mysql support (4.1 or 5.0).

hope everything goes okay.

but if not, at least you'll know what happened.

yes, i made a complete site back-up.

they said it should be painless.

i'll let ya know when it's done.

Good luck with the move.

Seven weeks ago my host told me they were moving my site to a new server.  Turned into a disaster.  Everything broke.  I ended up dumping them and moving my couple dozen domains to a new host.

To add insult to injury, they didn't move when they said they were going to.  They "pre-migrated" everything, then didn't flip the switch for a couple weeks.  By the time the new server went live, all my pages were a couple weeks out of date, links and scripts didn't work, and by then I was on a two-week vacation in a rural valley in Hawaii, with no internet access and no cellphone service . . . REALLY bad time for all my websites to break!

Here's hoping your move goes without incident.

Update on the site move (copy-n-pasted from home page):

The site move (to a new, updated server) mentioned yesterday involves a new name server (they say), which means the site might (not sure yet, I asked) be unavailable for a period of time following the move.

Okay, they said the new name server *will* need to propagate, which means the site will be unavailable for 24-72 hours, depending how far away from Los Angeles you are (where the Rad server is physically located). I'm making a *second* full-site back-up right now. =)

DNS propagation time has a lot more to do with what the refresh time is set to and when the cache expires for any server that might have cached it than physical distance.

Here's how DNS works:

1. You ask your DNS server for the IP of a website - radified.com.
2. Your DNS server doesn't know.  It asks the root server for .com.
3. The root server tells your DNS server that it doesn't know where radified.com is, but it does know that the Name Sever for Radifed.com is ns.somenameserver.com.
4. Your DNS server asks your name server what the IP is for radified.com.  The name server does know the answer, and provides both the IP address and a length of time your DNS server should remember (or cache) the answer.
5. Your DNS server replies to you with the answer.

Whenever you make a change to your zone file (DNS information) on your name server, your name server gives out the new information immediately.  However, some DNS servers out there already have the old, cached answer and don't know that the IP has changed.  When the timeout expires, 24-72 hours later, the DNS server will query the name server and get the new answer.

Usually, your hosting company will set the cache timeout to something really low, like 1 hour, a few days before they make a change.  Then, within an hour of the change, all cached information on other DNS servers has timed out and they will get the new information.  If they haven't done this, you could ask them to do it.  They might say no, but if they are as good as you say they are they might be willing to do it.

Any end user wanting to get to your site after the change could simply ask their ISP to clear the cache on their DNS server.  Some ISP's may be unwilling to do it, just because clearing the cache every time any website anywhere on the internet moved would be crazy, but you might get lucky.  Or, you could simply use a different DNS server that has the new information, if you can find one.

Thanks for keeping me honest. I updated the home page to correct inaccuracies.

The idea of propagation, to me, conveys the idea of a pebble being thrown into a pond, where the ripples "propagate" outward from a central source (the name server).

I think that if you are reading this, you have made it to the new site.

Nope, I can't access it either.
I get "The page cannot be displayed" screen.

Try *Ctrl + R* when you get the error page--it refreshed *something* and the page opened fine after that!

On one page, I had to close the browser, re-load the browser, and do the *Ctrl + R* a second time on then it worked.

you guys remember when we were getting errors when posting pleo's full name, and dot-htaccess?

well i had the same thing happen today when making a *blog* entry:

http://blogs.radified.com/2007/05/website_move_new_server_mysql.html

if you scroll down near the bottom, you'll see the word htaccess in italics, blockquote.

i had to remove the dot before the words htaccess, or the blogging software would give me an error.

took me a while to figure that out.

i remembered our problems here, which helped.

i'm guessing this is some kind of security protections against those files generated by *scripts* .. cuz both the blog (*.cgi) & this forum (*.pl) are both generated by scripts.

i could enter those words on the (html) web pages no problem.

but i was geeting 403 errors, saying i didn't has authorization to the blog script (which obviously i did, cuz i was using it).

i first thot something in the new server screwed up the blog (sweating bulltets).

started adding a paragraph or two at a time, until i found the culprit (just like we did here).

Interesting!  It's always good when you've had a similar problem before that you were able to solve--the second time usually goes much faster!

LunarPages seem to have a really overaggressive set of mod_security rules in place.

A quick google on lunarpages and mod_security turns up lots of people with similar problems. You should be able to ask them to turn off the filtering for your blog posting script if they don't let you manually tweak the mod_security settings for yourself.
