Do you actually have a route to their web site? That is, how do you know
they are reachable from you? Do a traceroute:

    tracert www.hotmail.com

I got the following (but this for today and may change depending on which
real host gets reached through the DNS lookup):

  1 1 ms <1 ms <1 ms (info removed)
  2 10 ms 8 ms 10 ms (info removed)
  3 10 ms 44 ms 9 ms bar01-f1-1-0.broohe1.mn.attbb.net
[24.31.1.141]
  4 10 ms 8 ms 10 ms 24.31.2.107
  5 20 ms 19 ms 20 ms 12.118.239.77
  6 22 ms 21 ms 22 ms tbr2-p012301.cgcil.ip.att.net [12.123.6.13]
  7 63 ms 63 ms 64 ms tbr2-cl1.st6wa.ip.att.net [12.122.10.62]
  8 103 ms 60 ms 62 ms gar1-p370.stwwa.ip.att.net [12.123.203.177]
  (followed by repeated timeouts)

So I can't even get to them today. Well, no wonder why when they have me
bouncing from the Midwest USA to Sweden (which then would pawn me off to
some login.passport.net host probably back in the USA)! When I do a
traceroute from http://lava.net/support/utilities/traceroute.html or
http://www.opus1.com/www/traceroute.html, it succeeds and gets to a msn.net
boundary host. So *I* don't have a working route to their server from *my*
location; i.e., their server is up but it is unreachable by me.

If you do a lookup on their domain name, www.hotmail.com, you get several IP
addresses returned. I got the following from "nslookup www.hotmail.com":

    207.68.172.239, 207.68.173.245, 207.68.171.233

If you do a reverse lookup on their IP addresses, you find they don't equate
back to www.hotmail.com. A reverse DNS lookup on each IP address returns
"hotmail.se". Like who the hell is that? The WhoIs services at Verisignand
Network Solutions return no registration information for this domain name
(i.e., no match). IANA lists the ".se" ccTLD (country code Top Level
Domain) IANA lists as managed by the Swedish site of http://www.iis.se/ but
does not list their WhoIs server. Didn't find a WhoIs service there but did
find a link to http://www.nic-se.se/ where I could enter "hotmail.se" and
see its registration data did list Microsoft as the registrant. On other
days, an Akamai server was listed for a reverse DNS lookup on Hotmail's IP
address and a traceroute died at the Akamai boundary host (Microsoft uses
them for Windows Update distribution but might now be using them for more
functions). I haven't a clue why Hotmail is bouncing request to servers all
over the world in the DNS records for them.

Have you called your ISP's tech support? When asking them if they can
traceroute to www.hotmail.com, make sure they do it from your regional
network hub and NOT from wherever they are. Tech support centers are not
where you are. Having them detect a good route from them doesn't help you
any. They need to go through a proxy in your area so they same routing
table gets used as is used by you from them. Unless they take the same path
as you, a traceroute from them means very little. However, if a traceroute
from them also fails then you compare their's and your's to find at what
point your routes join since from that host down to the target site would
then be suspect.

If you can use traceroute utilities from hosts in other regions (see
http://www.geektools.com/traceroute.php) to reach a host but a traceroute
from you fails then you need to call your ISP to find out what is wrong with
their routing tables. They need to mark the current route as dead and find
another.
