RE: Yahoo! Mail/Sys Admin
by Justin Wilson 04 Oct '07

04 Oct '07

We've been having trouble sending to *(a)yahoo.com Getting the infamous 421 Message from (x.x.x.x) temporarily deferred - 4.16.50. Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html. When I follow the referred link I get to http://help.yahoo.com/l/us/yahoo/mail/original/abuse/abuse-60.html, which then points you to this URL: http://help.yahoo.com/fast/help/us/mail/cgi_defer which is supposed to be a form. Sadly, that link loops you back to the Yahoo mail login page. Once you login your choices are quite limited and are for basic E-mail help. I've tried contacting yahoo through those links but I get a canned reply. It's been over a month of consistent deliverability issues to Yahoo and we're not one step closer to solving the problem. The one thing I did notice is when I modified SPF to include the IP address instead of the domain of the deferred MTA, E-mail would get through, but only for a few days then it was back to deferral. I've read the older posts on NANOG and various gripes about Yahoo greylisting on google but all the leads have come to a dead end. Does anyone know an interactive yahoo contact they could share with me? Thank you, Justin Wilson

Myanmar Internet turned off
by Steve Gibbard 04 Oct '07

04 Oct '07

There have been several news stories today about Myanmar's government turning off the country's Internet connectivity to suppress news coming out of the country (for instance: http://www.nytimes.com/2007/10/04/world/asia/04info.html?ref=world) Doing some poking at it earlier today, here's what I found: The .MM top level domain has disappeared. It's served by three name servers: ;; AUTHORITY SECTION: mm. 172800 IN NS NS-MM.RIPE.NET. mm. 172800 IN NS NS.NET.mm. mm. 172800 IN NS NS0.MPT.NET.mm. ;; ADDITIONAL SECTION: NS.NET.mm. 172800 IN A 202.153.125.17 NS0.MPT.NET.mm. 172800 IN A 203.81.64.20 NS-MM.RIPE.NET. 172800 IN A 193.0.12.151 ns0.mpt.net.mm is in Myanmar, part of the network of Myanma Post & Telecommunication. It's unreachable. ns.net.mm is in address space registered to Powerbase DataCenter Services (HK) Ltd. in Hong Kong. It's also unreachable, which makes it difficult to confirm whether its physical location matches its registered location. It may also be in Myanmar. ns-mm.ripe.net is in Amsterdam. It's reachable, but is responding to all queries with a SERVFAIL response. Presumably, this means it hasn't been able to get updates from a master server for the .MM domain for long enough that its data has expired. Looking at the rest of Myanmar's connectivity to the outside world, Myanma Post & Telecommunication has two IP address blocks registered to it: 203.81.64.0/19 and 203.81.160.0/20. Both of those blocks were in the global Internet routing table on September 27, but but have not been since September 28 (according to daily snapshots of route-views data). It's pretty safe to say that Myanma Post & Telecommunication has completely turned off its connection to the outside world. This is no doubt following the example set by the King of Nepal during the coup there a couple years ago. The New York Times story says there are two ISPs in Myanmar. Myanma Post & Telecommunication is the only one with IP addresses registered to a mailing address within the country, so I'm not sure who the other one is, or what its status is. -Steve

Rudimentary IPv6 Progress Report Page
by Mike Leber 02 Oct '07

02 Oct '07

I've been messing around with parsing MRT format IPv6 BGP tables and saw Randy's posts about deployment progress (or lack thereof), so I threw together this site: http://bgp.he.net/ipv6-progress-report.cgi It gives a rough estimate of the percentage of: * Networks that run IPv6 (currently 3%). * IPv6 reverse DNS servers that are reachable via IPv6 (currently 31.6%, believe it or not, most are only reachable via IPv4). If you have IPv6 reverse DNS servers, do they have an AAAA record for themselves? * ISPs on the ipv6tf.org ISP list with IPv6 websites (currently 32.2%). (I'll be the first to admit that Hurricane has a bunch of sites that need to be fixed to work with IPv6, we just added an AAAA record for bgp.he.net before posting this.) * Alexa 500 websites that are IPv6 enabled (currently 0%). The site is a work in progress. Feel free to send me suggestions.
