is this what an oversubscribed area looks like? pings have been pretty terrible since the start of term.

Postcode is SO17

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Could be, parts of the Southampton area are over subscribed (mine for example :( ) The avg & base latency (gren & blue) are all over the place which indicates there may be more in the mix. Can you post your up and down stream power levels from the Superhub status pages? On my Superhub 2 (in modem mode) they are here:

I'm stuck with a SH1 so theyre on a different page: http://i.imgur.com/QihZKWn.png

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

upstream power looks fine. downstream power is a bit high which may account the latency jumping around. Saying that snr is good and not too many pre-rs errors (although this does depend on the last time these were reset)

What sort of speeds are you getting in peak times? These are best done over wired connection and (if you have 100M+ product, using a gigabit adapter).

Saying that, SO17 is right in the middle of University land so you may be affected by the student population returning as you mention ..

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Ah where's craigy's compositor site when you need it...

Still. I'm surprised to see so many people (practically 100% of posters) affected by a single node being fux0red on VM's network, BT has at least a half dozen ways into LINX for example.

The appearance would suggest a link going down at 1am and failing over to a much lower capacity path and remaining there. Or perhaps autonegotiation cocked up and a 100GbE pipe decided to cut itself down to 10GbE (Does that even happen? I've never worked with >10GbE myself, but I know 10GbE transcievers *can* revert to 1Gbps)

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I'm not having any speed issues with servers through telehouse/linx, but having the bad latency issue.

Yeah - None of the 11 Portsmouth CMTS's are showing high latency. I suspect the pinging server peers with Virgin via a different edge router and isn't showing the latency issue some of us are having.

what is interesting is that two endpoints serviced by the *same* CMTS (sotn13) are different: one affected and one not:

http://www.thinkbroadband.com/ping/s...09-10-2014.png

http://www.thinkbroadband.com/ping/s...09-10-2014.png

What is interesting is the routing to the same CMTS. Here's the first "good" endpoint:

and the second "bad" one:

The interesting stuff happens around hop 12+ ... they take different network routes

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Indeed.

---------- Post added at 17:29 ---------- Previous post was at 17:28 ----------

Not entirely unusual. They're already taking different routes by hop 9. Variability can come down to random load balancing, or the fact that routing is done by destination IP range not destination physical location.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

TBH, it only started at 1am this morning, them acknowledging it within a day is far better than the north-of-Manchester core congestion that went on for a month...

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Awesome cheers! Looks like it's peered at a different node in LINX than the one having issues?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

very possible.
Its on a VPS in a IOMark data center.

It peers at Linx on 195.66.224.2

If you give me the IP at Linx that is the problem i'll add it to www.ukinternetreport.co.uk so it gets graphed

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

To be fair this may be correct but it's not necessarily that simple, often there are many logical links on the same 'node' for private peering vs. public peering, as well as multiple physical links serving each logical link via bonded channels. Last I knew VM used many 10Gbps links into LINX (vs. BT who used fewer ports but running at 100Gbps). ---------- Post added at 19:47 ---------- Previous post was at 19:41 ---------- It's not actually an IP at LINX that's the problem. The problem appears to lie solely on VM's core network, on some link between their LINX router and Northants. 62.253.174.17 is a good IP to ping if you want to monitor it, although that's only affected when entering via London far as I can tell, traffic from my location on BT to VM bounces via Manchester in one direction and isn't affected (thus, the congestion seems to be unidirectional)

Can't be. Pinging the BBC I get over 100ms pings on some IPs which bbc.co.uk resolves to, and some normal pings for others. It's definitely not just TBB.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

He doesn't mean it's just TBB, it clearly isn't. However the problem does only affect some routes and TBB is one of the most obvious and prominent ones.

Here is mine for Surrey near Guildford. During this problem my speeds were down to below 2Mbits on download but near normal on upload.

Attachment 25769

Another example to add to the others above. The red patch is when I used MyVM to remotely reboot the router and it stopped it working completely!l I did a soft re-set back at home.

When I then did some tests (given latency was showing very high), speed was fairly normal but ping was a bit slow and more jitter than normal.
