In this case, 17 is both the protocol and port number. Confusing
coincidence :)

 No, that's the protocol number - 17 is UDP - not the port number.

IPv6 route annoucement

2014-08-07 Thread John York
Hoping to not start a war...

We (a multi-homed end-user site) are finally getting IPv6-enabled Internet
connectivity from one of our ISPs. In conversations regarding our BGP
config, the ISP has balked at allowing us to advertise our ARIN-assigned
/44, saying things like, do you know how many addresses that is!!??

Am I way off base in thinking this network size is not out of the norm? I
know it's a lot of addresses (19 octillion-something?), but that
assignment was based on the same criteria that got us a /22 in v4 space.
Should accepting a /44 in v6 not be equivalent, policy-wise, to accepting
a /22 in v4?

Thanks,
John

RE: BGPMON Alert Questions

2014-04-03 Thread John York
We have a registered prefix that was affected. The RPKI may have helped
though; only one BGPMON peer saw the mis-originated route. Much better
than being on the 10+ list.

note joels careful use of 'injected'.  imiho, 'hijacked' is perjorative
implying evil intent.  i very much doubt that is the case here.  it
looks much more like an accident.  could we try to be less accusatory
with our language.  'injected', 'mis-originated', ... would seem to
descrive the situation.

and, btw, how many of those whose prefixes were mis-originated had
registered those prefixes in the rpki?

Re: google troubles?

2013-07-10 Thread John York
We saw the same thing, but seems to be cleared up now. All our providers
that routed to Google addresses in ATL had the issue. We have one provider
that lands on Google addresses in DFW, and it was working.

...And now I see that it isn't completely resolved. Some Google apps are
still inaccessible via the Atlanta routes.

 Seeing lots of reports of people unable to get to many Google services.
  Seems to be affecting Comcast users disproportionately.  It's fine for me,
 but a lot of my staff are basically out of luck...but according to the
 Google Apps Status page, everything is fine.

 It's anecdotal, but it would seem like there's an issue based on these
 reports.

 Oh, and this:

 Anyone know what's up?  Fiber cut?  DC outages?
