hi all

nice dicrepance from swisscom side:

official ticket from 12:15:

[Work progress:] BBCS Services available again, we are still investigating
the reason. If there is  just a voice problem pending (doppel belegung,
übersprechen) then your customer have to reset his Adsl modem.

[Approximately expected repair time:] Next Update 16:00 am

"Der Fehler konnte isoliert werden, so dass er keinen Einfluss mehr auf das
operative Netz hat. Das Datennetz ist mit dieser Isolationsmassnahmne
stabil. Die genaue Ursache wird noch im Detail analysiert."


hmm.. do they know the problem or not??? i'm confused ;-)

lets guess what we have here:

the facts:
- about 50% of the adsl network went down, the rest was online without
problems since weeks
- layer1 link was down (from CPE side)
- i suspect that the BBCS backbone is based on IPSS since IPSS customers
were offline also during that period (best efford? ,-))
- we miss still some customers. swisscom advised to tell the customers to
reboot the router. we saw sometimes that this doesn't helped -> opening a
ticket resolves that problem.


sooo... now the big questions: what was the problem? did swisscom had a
problem on the DSLAMs? routing problem within IPSS?

anyone from swisscom able/willing/allowed to give some technical
informations?


greetings
