Unless I am very much mistaken, Swissinfo is currently offline because of DNS problems. Or so it seems.
I noticed a few minutes ago that NetNewsWire reported some error for the swissinfo.org domain. Tried to surf the site with Firefox and indeed, I got a “Server not found” (or rather “Servidor no encontrado”) message. So I used dig to verify that no DNS record is returned.
Some more debugging showed, that the domain is still active and points to the two DNS servers NS1.IP-PLUS.NET and NS2.IP-PLUS.NET. But those domain servers don’t return anything for swissinfo.org queries. It seems, that IP-Plus has somehow misconfigured their DNS servers. Or maybe Swissinfo didn’t pay…
I will notify the technical contact for the domain by e-mail, just in case he doesn’t know about the problem, yet (very unlikely though).
Update: Definitely some IP-Plus problem. Checked swissinfo.ch, which lists the two name servers leo.srg-ssr.ch and ns1.ip-plus.net. The srg-ssr.ch one returns the names correctly (194.6.181.128 for swissinfo.org and a CNAME to www.swissinfo.org.edgesuite.net. for www.swissinfo.org). The IP-Plus one doesn’t return any data for any of those domains.
Update: As Matthias noted in the comments, Swissinfo was online again a few hours after my post.
