Chiba Kotsu Marronnier Bus to Ustunomiya

Hi, I've been trying to access Chiba Kotsu's website and the link to Marronnier's timetable but the website failed to load. Even the direct link to the timetable file failed. The following links are what I tried. Is the company still in operation?

I'm intending to travel to Utsunomiya from Narita Airport and from my understanding, Chiba Kotsu is the only transport service that offers a direct route. Anyone with news of whether Marronnier/Chiba Kotsu is still in operation is much appreciated. Thanks!

"Marronnier" bus is operated
jointly by Chibakotsu and Kanto Transportation (known better as Kanto Bus).

The bus timetable got revised coincidentally on today, March 28.
(That seems not related to your trouble in accessing the website.)

I can reach the two webpages of your links,
starting from the top page of Keisei website (http://www.keisei.co.jp/).

Anyway, it sounds better not to assume a public service is discontinued just because you cannot get to the official website.

It is unclear why you can not open it with your terminal(PC, cellphone),
but neither this bus company nor "Marronnier (gou*) bus" has been abolished.
Chiba Kotsu has reached 110 years since its founding last fall, no worry.

The 4th image is not Chiba kotsu web and not on yr travel date,

*)
This "gou(go)" is not english, but a bit important when you read Japanese,
one of major suffix, you will be see it many times.
