Service Unavailable Error 503 on my hosted domain!

[#1]

I get a service unavailable error message when visiting my site http://www.sounds-familiar.info. When pressing refresh it loads normally. 
Anyone have any idea's as to why its doing this? I don't want the crawlers to miss it!

Just tried to load it and it is sitting there saying Loading Google Analytics then doing nothing but still not loading - a refresh works immediately
Cleared cache and tried again - same error message you had and refresh works immediately or not.
Sometimes needs a couple more refreshes

[#3]

Just removed Google Analytics code from the header. I think it works now... will have to do without it if it causes this
Does it work for anyone else now without refreshes?

No it doesn't - same error and refresh fixes it

[#5]

First time (before you changed things) I got the 503 error. Worked with Ctrl+F5 refresh, and worked several times afterwards (no more failures).
Your new reply came up as I was about to post - tried again then and got the 503 error. Worked again with Ctrl+F5 refresh, and also worked in several attempts since.

I needed to restart the browser cache for it to fail again

[#7]

Taken one of the google ads out
Does it work now?

[#8]

Not first time again. As before worked with Ctrl+F5 refresh. But this time the error repeated and needed a second refresh, then OK for subsequent accesses.

Its hosted on the PN ccgi webspace. I dont see any issues on the Service Status page... anyone from PN know of any issues? 503 Errors are normally server end

Looks like one of the servers in the ccgi cluster has gone down, so the 503 is intermittent.

@Gabe - Do you have a link that you could give me for the ccgi cluster status? I used to have one for a long time, but it stopped working a couple of years ago.
This might possibly be related - although it is unlikely.

@Tony Nope, just guessing from the symptoms. There are other possibilities, but that would be first guess.

It was a problem this side folks and /is/ related to the thread here (ref: 73582). Some storage mounts had gone awry. The service was restarted this morning around 11.30am'ish and has been alright since then.

I'm still seeing intermitten 503s

Just got back from lunch and noticed this myself Gabe. I'll give somebody a nudge ...
