This web page still says that Vostok time is UTC+07:
https://www.aari.ru/ekspeditsii/rossiyskaya-antarkticheskaya-ekspeditsiya-(rae)/vostok
Could you please fix that web page? That would help confirm the change,
so that when people ask us for our source, we can direct them to aari.ru.

OK. Did clocks jump back from 00:00 today to 22:00 the previous day, or
from 02:00 to 00:00 today?
Also, could you please briefly say why Vostok changed from UTC+07 to
UTC+05? I would like to document this in commentary.

Ouch. TZDB has been wrong for Vostok for at least 10 years. I will try
to correct this.
(I hope you have not been at Vostok for 10 years! I'd rather live in
Siberia, or even in Nebraska. I can joke about this, as I was born in
Nebraska....)
Attached is a draft patch to TZDB to implement these changes. Please let
us know if you see problems with it. I have not installed this patch
into the TZDB development repository as it is still preliminary.
