IPv6 Ignorance
by Seth Mattinen 08 Oct '12

08 Oct '12

I came across these threads today; the blind ignorance towards IPv6 from some of the posters is kind of shocking. It's also pretty disappointing if these are the people providing internet access to end users. We focus our worries on the big guys like AT&T going IPv6 (which I'm sure but they're slow), but these small operators are a much bigger problem. http://forum.ubnt.com/showthread.php?p=355722 http://forum.ubnt.com/showthread.php?t=53779 ~Seth

http://bgp.he.net/net/100.100.0.0/24#_bogon A surprising number of large transit ASes appear to be more than willing to accept this prefix from AS4847. I'd be a lot happier if there were fewer. thanks joel

news.google.com (and others)?
by Barry Shein 06 Oct '12

06 Oct '12

This has been going on for days. We couldn't get thru to news.google.com but most everything else works. Once in a while it works. Connection is through towerstream.com. Traceroute usually seems to go through, sometimes dies somewhere out there past their network (72.14...? maybe abovenet?), no consistent result. Tried downforeveryoneorjustme.com, it says it's up. Called towerstream support, they couldn't get thru either. WAIT! The support guy had a tablet on Verizon 4G, he couldn't get thru to news.google.com using that either. He also said he couldn't get thru to google street maps, but google mail was ok (I can reload gplus.google.com no problem.) My iphone via AT&T has no problem, loads news.google.com immediately. Anyone else seeing this? I'm in Boston, Towerstream support is in Providence, RI. I'm thinking some sort of localized problem but trouble thru towerstream and verizon? It was passed to the engineer on duty at towerstream who will look into it and speak to google if necessary, not clear it's their problem though, not if Verizon is actually also having the same problem. -- -Barry Shein The World | bzs(a)TheWorld.com | http://www.TheWorld.com Purveyors to the Trade | Voice: 800-THE-WRLD | Dial-Up: US, PR, Canada Software Tool & Die | Public Access Internet | SINCE 1989 *oo*

Those who know Fred and knew Jon personally might want to throw an oar in the water on this blog posting from last month... http://esr.ibiblio.org/?p=4591 And that's not mentioning, of course, the people who want to throw the oar *at* ESR: I know he's a polarizing individual. :-) Cheers, -- jra -- Jay R.
