BTBroadband DNS? problems

I can't connect to one particular website, which I need to, for work
reasons. Everything else appears OK.

Tried another computer, connected to same router - same result.

Plugged in directly using the ADSL modem - same result.

Connected via InfraRed to my mobile phone to Vodafone - site works
fine.

Therefore I assume some kind of BT network issue - can anyone advise?

www.flextronics.com but I know it works in ways other than through my
home BTBroadband connection.

Discovered I can't ping Flextronics IP address 205.173.129.11 -
everything else seems fine?

I'm at the limit of my knowledge (it wasn't a long journey!) and would
be glad of some ideas.

Works fine here in Hove. I'm on BT Yahoo! Broadband via original green frog
and use the 2.2Mbps service. HTH slightly?

Sometimes a server is configured not to respond to pings, so by
itself that's not necessarily a problem. I tried pinging it, and
get no reply, however, I did get the website to load OK here.

You can get something similar from the MS-DOS command window using
tracert <host> or tracert <IP>

PingPlotter is quite handy, because you can get it to automatically do
tracing every few minutes, for example, and it does a graph showing the
times for each hop on the route. In the past I've known some hosts not
to be available for users of one ISP. It's possible a router somewhere
is not sending the packets back down the correct connection, but it may
be on ome network overseas and not your ISP's fault (but bringing it
to their attention may get it fixed). Good luck!

So this is what I get - it ends 'Destination Address Unreachable' (I
know that, just don't know why!).

I'm on BT Broadband 2Mb using a btbroadband.com DSL login and I can't get to
it either

Speeds have been terrible for me for months i.e. sub 1Mb

According to my router error log, a Zyxel Prestige P650-E1 there is no DNS
server available at various times throughout the day
55 Fri Mar 10 12:00:02 2006 PP17 INFO No DNS server available

No more info other than that

Just got this trace using WinMTR

Thanks for that - I saw the thread you contributed to on Jan 22nd,
which made me think this might be the issue.
