I'm currently seeing on two completely independent mail platforms
incoming mails from newsletter4-bounces(a)moneycab.ws, which seem to be
out-of-office replies sent back to the mailing list and
redistributed again... you get the idea ;)
I suggest you check your smtp logs whether you or your customers are
also victims of this sender, and act accordingly if you are.
from=<newsletter4-bounces(a)moneycab.ws>, relay=ml05.ispgateway.de [22.214.171.124]
(I wouldn't assume the relay to be constant though). At least one
mailing list currently being part of this problem is:
"Swiss Leadership Forum - Newsletter vom 30.04.2012"
nice to know Swiss leadership doesn't know how to deal with buggy
exchange out of office replies :)
Hi again Swinog members,
Many thanks for the many informative replies.
Some or maybe most (random sample) of the /48s in the routing table are not PIs - needs further analysis.
Regarding the PI suggestion, what do we do with customers who will never have an own AS and will never be dual homed? Do they have to "resign" to using Provider space - with renumbering when they change Provider. Or is there another way?
I know of this document which seems to tolerate /48 prefix propagation (even if the case described is not exactly our case)
http://www.ripe.net/ripe/docs/ripe-532. Does this document mean anything to SPs out there?

Deaggregation and PIv6 prefixes (which are /48s usually).

If you were my paying customer insisting on getting a /40 or /48 from
your PA space announced I would of course do so. But that's only half of
the story, because others have to accept that. And there will be
networks that don't.
There is no real consensus on if and how much deaggregation from PA
space should be allowed. As long as that is not there, we are filtering
>/36 from PA space. And I know others do, too.
If you absolutely need to do this, make sure you announce the covering
/32 somewhere. And make sure you do everything possible to prove the
validity of those routes (proper route6-objects, maybe RPKI ROA, ...)

Hi SWINOG members,
we're a LIR, we got a /32 from RIPE and we want to allocate /40s and /48s to customers. Only snag is that the customers will not have their Internet feed from us but from any Service Provider of their choice. The customers will have to convince their SPs (X, Y, Z) to route these "non X,Y,Z" or "foreign" prefixes. We're getting a lot of "raised eyebrows" about this. What's this about prefixes longer that /32 not being propagated? When I look at the IPv6 table I see:
IPv6 Routing Table Summary - 8625 entries
5 local, 2 connected, 3 static, 0 RIP, 8615 BGP 0 IS-IS, 0 OSPF
Number of prefixes:
/0: 1, /8: 1, /10: 1, /12: 1, /16: 1, /19: 2, /20: 5, /21: 3
/22: 5, /23: 5, /24: 7, /25: 4, /26: 9, /27: 10, /28: 31, /29: 19

So where did all the /48s come from ... also one or two /40s... ??
What do you think about this? If you're a SP would you route the /48s or /40s from the customers? What about your upstream peers?
Thanks in advance for your answers.

We currently face an excessive amount of open/closing connections on our webservers (dozends of servers showing the same thing) and it is going to all different domains and different files, looks like massive connection aborts going on.
Does anyone know if a large ADSL/Cableprovider is having problems? We do not see packet drops at our Firewalls at all
