Slow Site and 504 Errors

I’ve noticed that my website, running wordpress, has been very slow lately.
It’s currently down with the following message:
"Gateway Time-out
The gateway did not receive a timely response from the upstream server or application."
Thanks in advance,

Edit: I should have realized I was posting in a discussion forum. At the time, I thought I was creating a support ticket.

Bradley, I think I talked to you in IRC :slight_smile:

If the upgrade to PHP 5.3 doesn’t help, please do open a ticket and we’d be happy to help you out.
