Hey Folks
My NTL BB has difficulty connecting to irish sites, aerlingus, irishrail,vodaphone, boards, iol etc, i get timed out connections and it seems slower.
no issues with anyother sites, just those related to ireland.
Forgive my ignorance but could this have something to do with how NTL connects with the rest of the Irish network,if so what can done about it, because it wrecks my head?

When did this problem start happening, was it yesterday?

There was a thread yesterday about how NTL connects to Irish sites and they changed the routing to boards.ie, perhaps they are changing the routing for all Irish sites now:

http://www.boards.ie/vbulletin/showthread.php?t=262477

Basically, NTL doesn't peer for residential customers in the INEX (Internet Neutral Exchange) here in Ireland, instead all traffic destined for Ireland goes to the UK first, before returning to Ireland.

This is the opposite to most other Irish ISPs who peer in INEX and therefore have better latency to Irish servers. However the slightly higher latency on NTL certainly shouldn't cause you to time out.

What is weird is that NTL actually holds the Chair at INEX and have been members for years. It seems they use INEX for their business traffic, but not their residential traffic.

However yesterday when I posted about this, suddenly traces to boards.ie started been routed through INEX and the pings went from about 40ms to 14ms , however all other Irish sites remained the same as before, maybe they are changing that now.

Next time it goes down try to ping the site or access it by the IP address.
See if that works.

Go to Start->Run and type CMD hit return. This will pop up a MS-Dos command prompt dialog. Type in tracert www.boards.ie hit return

You should be able to find the route your taking to access boards.ie and where it falls over. As you can see that is the route I take to boards.ie. NTL will take a different route than the above route.

If you have a problem you will see it and the location, then you can ring NTL and give them the info.

My pings to boards have dropped from ~35ms to 14ms since the change bk mentioned yesterday.
Pings to jolt.co.uk remain unchanged.
