currently we have a website that used to be running on Linux Suse and currently it is down.
We need someone who has Linux as well as varnish cache server expertise to take a look at the server. Basically when we go to our website we see the following error message;
Error 503 Service Unavailable
XID: this keeps changing every time i refresh page
Varnish Cache Server
Could you please respond if you already have the skills and fixed these type of issues before;
