I have an ongoing saga with my internet connection; where the latency periodically goes through the roof. In most cases, this seems to coincide with something uploading data.
I'm not having a lot of joy with the ISP (Sky), so I'm trying to do my best to gather information that might help. First off, I need to figure out if this is normal. I don't remember ever having this sort of problem in previous properties; but our phones didn't back up every photo/video recorded then (and we didn't have kids, so there were less of them!).
It's an ADSL connection; downstream is 11Mbs, upstream is 1Mbs. The usual culprit is Google+ on Android doing AutoBackup of photos + videos.
Here is a graph of ping times to the router, google.co.uk and sky.com for 20 minutes. The first 10 minutes there was nothing uploading (just some general surfing, and background chatter from a PC, two smartphones, two tablets). The second 10 minutes is during an auto-backup of a video to Google+ (which seems to take far longer than I would expect).
Timeout was set to 5 seconds; and all timeouts are recoded as 10000 in the data (so they go off the top of the chart). Both Green (Sky) and Red (Google) lines are pretty consistent, so the red line is mostly obscured by the green. The blue line has only one ping that was high at 2000ms.
The problem obviously isn't just that ping returns high numbers; the connection is utterly unusable during this time.

Is there something wrong; or is this normal for ADSL? I can imagine that Google might be able to receive my data faster than my line can transmit it and saturate the upstream; but I would expect people to generally be unhappy with ADSL if this was normal?
If it's not normal; any further tips on providing info that might help Sky investigate/fix it would be welcome.
Here are some router stats if they help. The initial line testing (DLM?) started at 2Mbs and went down, so someone at Sky manually set us at 11-12Mbs/1Mbs based on these stats.
