[Javascript] Time & day-based redirects?

...because if the server is down, there will be no way for that message to
be calculated...
In the same way it's not very useful for your email administrator to email
you that email services are not working... <g>
If the "Server" under maintenance is a _database_ server, and the _web_
server remains functional, then you're right - that code can run smoothly on
the web server while the database server is under maintenance.
If you have a NAT firewall/router between the user and the web server, you
could redirect the traffic to an entirely different web server - but unless
you can automate that process, it's pretty likely that the process won't be
done reliably.

well, if you are running a large site then you are using a server side
language more then likely or even Server Side JS. Why not just do
something
like:
IF dayofweek(now()) = Monday and 0200 < now() > 0700 THEN
{
print "
<SCRIPT>
alert('Site is down for maintanence');
</SCRIPT>
"
}
Or even better yet, like i do. I have a table in our db for all the
default
settings of the website. In there i have:
Columns: main_siteDown, main_siteDownMsg
Values: 0, "Site is down for maintenance"
And then from a web page that we only have access too, I can change the msg
to whatever and set the main_siteDown to 2. All accounts are locked out
except Admins. Setting it to 1, displays the msg, usually saying "The
system is going down at whatever time" without locking ppl out.
But your time needs to originate Server Side since that is what is under
maintanence.
