Hi,
I noticed that trinitydesktop.org and bugs.pearsoncomputing.net are
unreachable from time to time from my location in Austria.
What can I do to overcome this?
The traceroute is like this
traceroute -p 80 trinitydesktop.org
traceroute to trinitydesktop.org (192.119.205.246), 30 hops max, 60 byte

Did AT&T outsourced to India :D
Thanks & regards

traceroute -p 80 trinitydesktop.org
Many firewalls will drop UDP 80. Try adding the -T flag.

This suggests that the problem lies in the routing of the
response packets, not the request packets.
I used the NTT [0] BGP looking glass (GIYF) to traceroute from
their Chicago router to your ISP's 178.191.255.254 [2] and got
no further than Level 3.
So over to Level 3's looking glass and a BGP check for your ISP's
178.191.0.0/16 shows no route.
So this is a problem for you to take up with your ISP. They need
to barter or pay for BGP peers to announce their ASN globally.

I chose NTT at random. If NTT had a route to you I would
have investigated further to see why Tim's return packets
were non-routable.

-T flag.
It does not change anything. The domains are still unreachable.
Very sad!

Thanks for confirming this. Looks like someone left a sh*T and cleaned up
later. The issue was just solved recently. Now it works again.
Indeed it looks like it was with the local provider, because from another
local provider I was able to reach it.
