am back on overlay now, just happened right now during the day. Thankfully also got my overlay ip back so was still in DHCP cache. So I simply turned the overlay tbb graph back on, no need to make another new one for it.

Legacy latency is overall lower, this morning during dusk it got very low, however when load is high on legacy the packetloss is unreal which has far bigger downsides than jitter and real world download performance is always way off what I get on speedtest.net so if eg. 15mbit on speedtest.net and then I download a file of a ftp server, that ftp download would be something silly like 1mbit with random stalling etc. On overlay speedtest.net tends to be close to real world performance not always but at least most of the time.

here is my last 24 hours on legacy.

my jitter and pings have been hovering 20-80ms all day with download speeds generally at 10-20mbit, browsing useable. Within the last 30 minutes tho it topped over the edge.

1 <1 ms <1 ms <1 ms home.gateway2 [192.168.1.1]

10 772 ms 790 ms 713 ms virtual-vip.thdo.bbc.co.uk [212.58.224.138]

Ironically in this state it is still more useable than the legacy network was. But throughput due to the very high rtt is now maxing out at about 2mbit and web browsing is very laggy. streaming on youtube even still works. speedtest.net with its 4 threads gives 7.21mbps which confirms the rtt limitation.

all looking good here guys....

However when I try download a file I dont get much over 600kb/s unless I download multiple files at once?

Chrysalis · 28-01-2011, 13:32

new fix date is 17 march for my port, last night was severely congested until after 4am. jitter jumps up around midday. On weekdays.

philce · 28-01-2011, 18:41

Tech visited today to "check things" under instruction of the CEO's office.

Nothing wrong with the kit here, just confirmed what we already knew, about capacity!

CEO's office now waiting for feedback regarding the upgrades, the tech seemed to think it would be sooner rather than later.

Chrysalis · 28-01-2011, 20:11

someone asked a question today on the VM forums about what UBR they would be on, the answer was as I expected, people in one given area can be routed to different equipment, this was the answer.

Quote:

There are four possible UBRs your modem could connect to in your area on that tier of service. 2/4 of the UBRs have utilisation issues that could impact your service.

They forgot to mention what Ignitionet and Nopanic have already said that it is no longer something that is allowed due to restrictions on the network and that after a fault or reboot it will retune to the correct uBR.

Chrysalis · 28-01-2011, 22:50

ignition was reffering to switches between docisis1 and docsis3 channels, here I am talking about actual different UBR's.

the post I stole that quote from she also said they cannot make sure they on a particular UBR, so even tho 2 out of the 4 UBR's for that area are good they wont intelligently make sure customers dont go on the oversubbed ones. Not very good management.

Chrysalis · 29-01-2011, 03:29

given that VM have announced upload p2p shaping trials now I do find this 17 march date a bit suspicous and am curious if its a real upgrade or something they can claim to be an upgrade based on a projected performance improvement from traffic shaping.

They will not swap you to a different uBR though because the system no longer allows it as a simple reboot will see you back on the original.

Depends how it's done.

It's actually more conditional on back end rather than faults or modem reboots. Have a look at how a modem on 10Mbps on the DOCSIS 3 network is provisioned then check one on the VXRs, making sure both are on L or M of course.

Chrysalis · 03-02-2011, 13:58

before and after graphs from old modem to superhub. both on overlay.

philce · 05-02-2011, 10:22

Looks like I've been bumped back to legacy! New TBB graph running.

CEO's office promise a resolution "this month".....

Ignitionnet · 05-02-2011, 10:27

That resolution consisting of them terminating your contract and telling you not to contact them again
