EDIT: The server was moved off of shared hosting after about 4 hours of release. It's now on a dedicated server with a 100mb port.
EDIT2: This is an old post and it's no longer on just one 1 dedicated server. It's on many, and utilizes a CDN provided by Voxel.
This was the original post  announcing the creation of imgur 7 years ago. Maybe in 7 years from now you have your own img42 image hosting emporium! :)
I have been hosting img42 off a $5 a mo/ droplet :P. It has served XXm+ impressions, and 1m uploads since its creation. I also have been sustaining a ~3m a day DDOS from Russia for about a year now.
