Just recently I have been seeing lots of packet loss on IPv6, but very little on IPv4. Any ideas what is going on?

Very similar to mine:

(Ignore the blocks of yellow in the early evening, that was me streaming Formula One :P)
I could never get IPv6 working on my parents' modem... Netgear DGN2200v4
Noticed this too, but I'm getting latency up to 120ms, average around 50ms; and speeds on VDSL2 have plummeted from 38Mbps down to around 7Mbps and uploads from 6Mbps to around 0.5Mbps. Even the TBW Tap 3 test advised reporting a fault, but IDNet Support (daytime service - has it been outsourced to India when I wasn't looking?) response has been to use the test socket to improve the upload. ??? How?? ??? I've disconnected the phones anyway.
Still it's the first time I've had to use support for a problem in five years so I suppose I'm lucky. Unless things improve of their own accord it looks like migrate (but risk the same problem locked into a contract, as I'd go for cheap n-cheerful this time, why anything else with the state of BTOR infrastructure?) or downgrade to ADSL as that's what I've got - well the download would halve but the upload would double!!
Does a downgrade get a cease fee, and a new lock period on the contract though, and what is it?
Meanwhile it's back to the good old days, limited to browsing and radio streaming!! Would happen just after I bought an internet TV (Why????). :rant2: Sadly my old (free, as I paid the whole capital cost my end) Fixed Wireless service has been disconnected. I didn't worry about it whilst VDSL2 looked good to go after over 4 years, so maybe the best course (talks to self) is to see if I can get reconnected for free too!! At least the air doesn't need any maintenance. :thumb: Sorry for the rant, it helps!!

Your plot is identical to mine since mid-night.
Email sent to Support.
edit- They're looking in to it.
Hi All,
So far we cannot see any reason why IPv6 would be having issues over IPv4. If you can ensure the line is idle and compare tests to the two addresses below and let me know the results that would be great.
ping6 www.thinkbroadband.com
and
ping6 mx1.idnet.net

Concurrent ping6's (at 2 second intervals) for just over half an hour:
Quote-- www.thinkbroadband.com ping6 statistics ---
944 packets transmitted, 933 packets received, 1.2% packet loss
round-trip min/avg/max/std-dev = 7.350/8.046/11.677/0.319 ms
Quote--- mx1.idnet.net ping6 statistics ---
944 packets transmitted, 944 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 7.326/7.931/11.065/0.275 ms
BQM was showing brief periods of packet loss up to ~10%
Line wasn't completely idle, but no downloading, uploading or streaming going on.
Also ran a test on this site (http://ipv6-test.com/pingtest/)- it's similar to the tbb BQM (ie it pings me) but only shows a live graph for the last 5 minutes and doesn't keep records.
Random packet loss on IPv6 (mostly single packets, occasionally 5 or more, correlates well with the BQM), very occasional lost packet on IPv4.
Hi All,
After a further bit of digging we have scheduled maintenance set for tomorrow morning at 4am.
Kind regards

Thanks Simon- I won't wait up ;)
That's better :thumb:

Yup, fixed here too ;D
