Anybody cares to translate this to english? Short summary: Zyxel

DSL routers were blocked by changes in some timeserver they were by
querying by default - which apparently meant that they didn't boot
through.
Tricky Internet Outage
Thousands of ADSL customers affected
This past Friday, October 13, a breakdown with a curious cause made
thousands of internet customers at probably all providers scratch
their heads. The source were ADSL routers made by Zyxel, the market
leader in Switzerland. Affected are 48 models from the P-650 and
P-652 series, about 10000 of which have been installed in
Switzerland, according to distributor Studerus Telecom. The problem
was only resolved on Monday: because of a preference setting the
routers queried a time server in Heidelberg for the exact time.
Since changes had been made to that server, the routers were blocked.
According to Marcel Meier, deputy General Manager at Studerus, all 13
employees working in the support department were overwhelmed with
support requests. Until Wednesday, a couple of thousand customers
had been given a solution by download or over the phone. Efforts by
providers were unconvincing: two of the large providers, Bluewin and
Tele2 didn't even inform their customers on their home page.

Official response from the Swiss Zyxel distributor:

Apparently, the name server configured by default is/was
129.206.119.11. According to a different article, "changes in the
date format caused some routers to reset when they queried the time
after establishing the ADSL connection." That would rule out NTP as
the protocol, it seems.
In their official response, the distributor suggests to use an NTP
time server instead of the Heidelberg one: 129.132.2.21. Wonder what
the ETHZ thinks about a commercial entity using their time service?
