Re: [Haskell-cafe] Weird reachability issue with haskell.org my my Italian ISP (fastweb)

I ended up using a machine running privoxy (using aws or similar) and that works, but I'm not sure I want to pay for the idiocity of my ISP. Happy new year all, anyway. Alfredo Di Napoli

Hello Cafè,

let me start with the email I've sent to Rackspace, which will help you understand the context:

...

Hi there!

...

I'm trying to understand how come I can't reach www.haskell.org from my ISP here in Italy (fastweb). In order to troubleshoot the issue, I tried dig on it, revealing it's hosted by you:

...

dig haskell.org

...

Trying a whois reveals the subnet is the entire 23.253.0.0 one:

...

Rackspace Cloud Servers RACKS-8-1387376775861482 (NET-23-253-80-0-1) 23.253.80.0 - 23.253.95.255 Rackspace Hosting RACKS-8-NET-15 (NET-23-253-0-0-1) 23.253.0.0 - 23.253.255.25

...

If I try to ping the IP directly, it obviously doesn't work, so I have tried contiguous IP addresses in the same subnet to see if the subnet itself was reachable at all.. trying 23.253.89.73 indeed worked! It resolved to http://www.papamurphys.com/ This means my ISP can reach that subnet, but doesn't explain why it can't connect to 23.253.242.70.

That's very weird indeed, as every other website is reachable, only haskell.org is not! How funny my fate is! I'm one of the few Haskellers in Italy and yet I cannot access the website.. perhaps is the consequence of "Avoid success at all costs"?? :) :)

Jokes aside, do you guys know (I'm asking mainly to Austin here) if rackspace uses some weird setup for their website deployment or if haskell.org is hosted "the usual way" and listening on port 80?

Thanks in advance for the 1% who is concerned, for all the other 99%, merry Xmas ;)
