Migrating Server

Yesterday, i moved one of my server on my campus to another ISP (we used two ISPs) because the other ISP had a hardware problem and they couldn't fix the problem within acceptable time frame (it's number two biggest ISP in this country ). The strange thing was that this server is still accessible from outside, but unable to connect to other site.

Since this server hosts several important sites, i had to react quickly and moved the server to the other ISP and since then, i have to wait for at least 24 hours for the DNS entries get propagated around the world. Right now, they are back to normal business and i can start updating my repositories back again
