We are in the process of bringing up a new web server.
We have just moved an existing zone from one Cloudflare account to a new one.
At one point we had duplicate DNS records in our zone settings for a host. One of the records had an invalid IP. We have now reduced this to a single IP (in the last hour or so).
Our website now appears to be working correctly however every now and then we are seeing a 503.
<html> <head><title>503 Service Temporarily Unavailable</title></head> <body bgcolor="white"> <center><h1>503 Service Temporarily Unavailable</h1></center> <hr><center>cloudflare-nginx</center> </body> </html>
Here is the trace against the site.
