[Pro] Can't access website, not in browser, not thru FTP

I am at my wit’s end as to what to do about this. All of a sudden, I can no longer upload files through FW to the server. Nor, can I access the server through an FTP app. In fact, I can’t even open in the site in a browser. But everyone else can! What is happening?

I have been back and forth with the IT person for the company, because they are getting ready to move to Google Apps, but he said he hasn’t done anything yet, and he can access everything.

I Googled (and Googled and Googled) it and decided it must be a problem with DNS caching. I cleared all my caches and typed in dscacheutil -flushcache in my Terminal to flush the DNS cache. No change.

I tried using the IP address instead of the ftp.domainname.com for FTP, but I still couldn’t get in. I want to throw myself on the floor and kick and scream.

Can anyone PLEASE help me?

Have you contacted the hosting company about this? Your server might
have crashed. What response do you get when you type in the address to
the server? Is a “host not found” or does the site try to load and
just spin and spin? What happens if you open Applications/Utilities/
Terminal.app and type in the following commands? (each one followed by
a return)

host www.yoursite.com

ping youripaddress

traceroute youripaddress

Naturally, fill in the demo stuff above with your real details.

This means that your computer is able to reach the server without any
trouble. These times are a little long, but nothing too worrisome.
Here’s another stupid terminal trick to see if you can reach the Web
site from your computer:

telnet yourserverip 80

The server may respond with a couple of lines of gibberish, ending in
Escape character is ‘^]’.

Then type:

GET /

(press return after each of these commands)

You should see a Terminal screen full of HTML code after the second
command above, and if you don’t, the error message might be instructive.

By the way, sorry about the ping command running on and on like that.
I forgot to give you the -c parameter, which restricts it to a certain
number of tries. Here’s what you would do in that case: ping -c 5 www.apple.com

I had a similar problem when trying to access a client’s site and
cPanel and was given the same response. I never got a clear
explanation as to what exactly happened. It was curious.

Unix servers generally run for years at a time without restarting, and
months between patches. It may be very true that he didn’t change
anything, but if you get used to everything just working that well,
for that long, you may be too lazy or lulled to check something
obvious, like maybe Apache is balled up in the corner whimpering to
itself, or similar. He may have put you off because he figured the
problem was on your end, not his “perfect” server. And his dashboard
may have said everything was green, too. But Apache can be running
just fine, and refuse all connections because it’s used up all of its
memory and can’t spawn a new worker. I actually did that to the OLL
server last month, twice in a row. Luckily, that server has a “robot
overlord” script that can reboot the entire server in an emergency,
the equivalent of pulling the plug out of the wall. I’m betting that
the ftpd process was stuck somehow. You could see the server, the
network ran just fine, but you couldn’t get it to answer on port 22.

Right. It’s buzzword bingo!

Interesting. Well, if this happens to me again, I’m going to say:

“Are you sure nothing has changed? Because, even though your

might say everything is green, an Apache server can be running just

still refuse all connections because it’s used up all of its memory

can’t spawn a new worker. Unless you have a “robot overlord” script

Of course, I won’t know what I’m talking about, but they might THINK
I do.
