File uploads are extremely slow. For example, a group of 3 x 20Mb files might take an entire day to upload on a 5mb.s connection. This has happened in the past 3-4 weeks.
I found the root cause of it. I am in New Zealand and redirected to the Tokyo server, which is very very slow. I verified that this upload path is an issue thus:
Tried to upload a 20Mb file using browser (via Tokyo) - 2 hrs later the file was at 20% upload. Cancelled the upload.
Connected a VPN onto Los Angeles. Uploaded the same file (and others). Uploads completed in less than a minute.
This performance issue forces me to use a VPN each time I use Box to upload which is burdensome.

Thanks for your attention on this.
