Dreamhost is giving more to their customers. They just quadrupled the disk space, and octupled the bandwidth.
So now, in my account, I have:
21780 MB Disk (Grows 160 MB / week)
Used: 256 MB (1.2% – Overage $.10/MB)
1071 GB BW per Cycle (Grows 8 GB / week)
Used this Cycle: 8.4 GB (0.8% – Overage: $1/GB)
Goddamn, they rock! A TERABYTE of bandwidth? That was unheard of for me till now… XD
