Finally, something affected that is *not* the ping monitor. About time too ;)

That's not the speedtest server though. The speedtest server is at gonzales.namesco.net

Re: Think Broadband Ping Monitor Results (POST YOURS)

High pings to facebook during this issue aswell as adslguide..

Pings to bbc and youtube fine.

Weird

Re: Think Broadband Ping Monitor Results (POST YOURS)

can I ask what that green spike actually means?

Re: Think Broadband Ping Monitor Results (POST YOURS)

as me and others said it wasnt a tbb only issue, just I been too busy before to do all this data collecting.

---------- Post added at 21:05 ---------- Previous post was at 20:59 ----------

tesco packetloss is gone now as well.

Re: Think Broadband Ping Monitor Results (POST YOURS)

we might be onto a double dip, as its subsided earlier than usual and I can see my graph going up again.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Triple dip by the looks of things. Please do http://www.thinkbroadband.com/tools/traceroute.html again.

I suspect the issue is at linx-gw1.router.ntli.net [195.66.224.22]

[Edit]
Yep, that gateway is overloaded. Both ports as well, though one more so than the other.

Too late, it's recovered again. Traffic got rerouted.

No it isn't.

I'll try those tracerts tomorrow. Been away from PC. Bump is ended for tonight.

Re: Think Broadband Ping Monitor Results (POST YOURS)

too late, although its the other return routes I am interested in as you already have seen tbb's.

going to contact the 2 isp's and ask if they can check my routing during an evening.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Doesn't really matter. We know where the problem is - 195.66.224.22. Everything going from LINX to VM's network through that is affected. Easy enough to find once people came up with actual evidence that it wasn't just TBB.

Incidentally 457 routes are advertised by that gateway.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Does BGP Play show anything?

Re: Think Broadband Ping Monitor Results (POST YOURS)

Well I'm sure after a few days of complains on their forums VM's cack network team will sort the issue out.
