airbnb not accessible from some IPs

[Guillaume41]

Hello all,

I have a really strange issue. From my home internet, I can access the main airbnb page, but after I login most of the pages return "503 Service Temporarily Unavailable nginx/1.7.12". This happens from my 2 computers and the Android app on my phone (the message is a bit different there: "Something went wrong with your request").

But from work it works fine. Also from 3G. Even more strange, from the SAME computers if I use my neighbor's wifi instead of my own, it also works fine. We both use the same internet provider. The traceroute to airbnb is the same in both cases except for a different source IP.

It makes no sense that I would get server errors based on my source IP. What is going on ?!?

I've checked my ADSL modem and there's nothing fancy in its config (no antispam / antivirus / outbound firewall). Other websites seem to work fine.

I've tried a manual DNS and the problem remains from home.

I have no idea what else to try.
