Fixed that for you.

Oh hey they're using themselves for international transit. Interesting.

The graph, yes. VM's routing cock-up, not so much.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

"Interesting" is putting it mildly. I suppose it makes a lot of sense, though.

You know. Assuming you don't cock it up.

Even my powers are limited :(

Aorta has 300Gb/s on both AmsIX and DECIX. Makes a lot of sense for VM to retire their own Amsterdam and Frankfurt peering, in turn saving on hosting and circuit leasing, and use the family's there and indeed in Paris and Ireland also.

Thanks to Aorta VM also now have public and private peering in the Czech Republic, Hungary, Austria, Romania, Poland, Slovakia and a whole bunch of sites they previously had no direct connectivity to in the USA, Germany and the Netherlands.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I'm assuming said peering can't perform any worse than their own previous routes... Plus what'll happen to VM's own fibre running from Manchester to AmsIX or was that leased?

In any case that level of reconfiguration isn't trivial, so I'm a little surprised it was "just done" without any fuss.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

peering can be worse than 3rd party transit in performance. Depends on how well its managed.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Leased. VM's only fibre outside the UK is the Sirius ring between Great Britain and Ireland.

Far easier than, for example, moving the Telewest AS behind the ntl one and, after that, merging them which was also 'just done'.

This is nothing more than editing an AS macro and some route maps. Looks as though it went slightly wrong, too, given Aorta was taking precedence over VM's own LINX peering for a little while. I guess this might perhaps be due to the pre-existing traffic engineering governing LINX and the TBB route on VM's edge.

Public peering is purely about cost, not performance.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I know its about cost, but his question was about performance.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Wise fountain of knowledge as ever.

Well, that took months, did it not?

Doesn't VM have dozens of ASNs though, and Liberty Global more still. Or do people still not sanity check/ACL their BGP adverts?

Only with regard to VM's prior Manchester <-> Amsterdam link, which was excruciatingly slow but heavily preferred by VM due to cost.

It was faster going Manchester => London => Paris => Amsterdam via external transit than Manchester <=> Amsterdam direct on VM.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

yeah vm had poor peering to .nl. I remember those days.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

looks like there was a hump tonight, showing on others graphs too.

my min latency rose slightly at the start of Tuesday as well.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Usually I have been unaffected by previous "humps" in these graphs but mine shows this too.

It's usually just an indication of congestion on the route used between VM and TBB but still hopefully it can be sorted.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

No? They have AS5089 and they supply transit for the odd customer who have PI address space.

Liberty are much the same. Bunch of ASNs they advertise for as they supply transit, including their own divisions and VM, but the actual advertisements are from 6830.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Guess I must have been getting ASNs confused with their prefixes, which they do have hundreds of...

Then again there used to be more!
