Lemme explain... I've been giving this some thought lately and am curious about other perspectives. My personal experience with DH's services has been a mixed record, but the most reliable service by far has been disk access. Through SSH and (S)FTP. And their backups appear to have been just as stable.
Through the magic of WEBDAV and SSHFS, I can easily open up that reliable remote storage to my users. Actually, I already do this but have been slow to migrate data to the new services enabled by this explosion of space(personal NFS!, remote backup as just two examples). In addition to disorganization, part of my slow adoption has been weariness over quickly becoming totally reliant on DH for access to my own data. Again, it's been their most reliable service in my experience but I don't have an SLA with these folks and data loss is THE original sin.
SO, I've been experimenting with different schemes that give me a bit of insurance. And I'm ready to open the taps a bit wider and begin to use more space. This all leads to a chain of thinking that leaves me hoping that whatever DH's formula for ("over")selling vs. growing REAL bandwidth is, it allows for a steeper "run curve" than perhaps similar formulas used by banks and the like when calculating what kind of reserves are appropriate.
(Information)technology sees incredibles spikes no? Think the use of video in the past 2 years vs. the 10 before them. While not known by everyone now, and used by even fewer, technologies like WEBDAV and SSHFS are already bleeding their way into Joe consumer's awareness. It's completely feasible to me that DH will see a noticeable spike in disk usage over the next year or two. I hope they'll be ready for it.
BTW, sshfs is much faster than webdav and has the extra bonus of not requiring you to have to setup https(and pay for a static ip) just to enjoy "secure" file services.
