Here's my situation: I bought a hosting account and SSL certificate at one hosting company. After the site was online 1 day, next day it's offline and the only page I see is IIS 7 welcome page. I was told that they are doing update server first (by one person) and after phone call after few hours I was told they are installing SSL certificate to my domain and that WHOLE server is down just because of this problem, which means that all websites on that server are down. I waited for another 10 hours but nothing happened, so I decided to check if this was really the case. So I found this website:
http://www.websiteneighbors.com
And looks like it really finds websites on the same webserver. I have opened most of these websites and they all work normally. Basically, my only question here is, how confident this service is? I need to have an argument but I am not sure if I can rely on this website completely. I have also checked DNS on whois tools and they match with my domain.
Any suggestion is appreciated!
PS Sorry for non-technical and "personal problem" intro

sudo /etc/init.d/apache2 gracefulwould reload the config files and no downtime and the SSL certificates would be active. – kobaltz Mar 13 '12 at 23:05
