Cloud backup restore - Connection throttled?

[tombacon]

I am trying to restore a backup from the cloud. I use Crashplan, and my backup is 5TB. My restore was running fine for (almost exactly) 24 hours, when suddenly my router restarted itself and when it came back online I was only able to download from Crashplan at 400kbps. My speed to everything else was fine. Speedtest was reporting 350Mbps, I could stream, game, and download all I wanted, except to Crashplan.

After trying several things for the following day, I eventually tried using a VPN, et voila, my speed returned (albeit about 60%, but y'know, VPN). Since making this change about 3 days ago, I've had to hop VPN servers 3 or 4 times as it will eventually returned to the slow speed until I choose a new server to VPN through, then it returns.

To me, this seems like Virgin are throttling my connection to high traffic IPs. Is there another explanation I'm not seeing? I have a list of FQDNs to whitelist if possible.

VM don't throttle traffic, and especially if you are using VPN's they don't know what you are downloading.  There are users here who regularly download TB's of data.  Have you checked with Crashplan?  It seems every time you get a new WAN IP it runs for 24Hrs and then slows down?  I doubt if that would be VM's doing?

It's not necessarily 24 hours, and the first time it happened (which was exactly 24 hours) my router restarted, which I doubt Crashplan was able to do, and then it became slow after the restart.

See what it looks like after 24Hrs. and post a link to the shared live graph for comments.

So are you suggesting that virgin media have developed the ability to break VPN encryption? I find that difficult to believe, most of them struggle to tie their shoe laces!
