Hi all,
I have been experiencing a lot of frustration with my Vodafone-supplied internet connection (via DSL) recently. The symptoms include a large number of dropped connections on HTTP downloads. These are on transfers of typically 600MB - 1.2GB per file, over HTTP, from a variety of servers. The files are legitimate media downloads (I do media processing as part of my professional occupation.) Up until around the last week of September, these downloads had been running at near-100% reliability. I'd set them up, and come back 2-4 hours later and they'd be complete and intact. However, since the last week of September, the connections on these have been dropping anywhere from 5 times per minute to 1-2 times per hour.
The typical connection error is: Connection reset by peer.
I have eliminated a lot of possible causes. I've tried different DSL modem, network config, downloading machine, OS and browser. No change. The problems occur with a variety of servers running over a variety of IP routes.
Now the question that must be explored is: is vodafone doing traffic management/shaping on my connection -- because if they were, this is the kind of result I'd expect to see.
For reference; I'm on a 30GB per month unlimited-speed plan from Vodafone.
Please weigh in; have you noticed *sudden* change in connection reliability of HTTP streams on your Vodafone-supplied DSL plan. I'm not talking P2P here, just a single client-server connection with a single server.
I would like to collect some more information and opinions on this before I put questions to Vodafone. Hints on how to escalate this appropriately past Vodafone's front-line call centre would also be appreciated.
Regards,Phil.
