I am assuming you are from Philippines based on your signature. I am also from the Philippines. My first server was in Savvis and the second is in Databank.
I have noticed that if you are using PLDT as your ISP, there really is trouble connecting to the servers in either datacenters. Multiple refreshes help, although a PLDT technician has suggested that you specify their DNS servers in your connection. It helped. I forgot the IPs though so give them a ring
I also have a Globe broadband connection and it has no problem connecting to both servers. No refreshes. So, based on that, it's an ISP problem instead of an LT network problem
