This Sunday 26/1/2020, access to Wikimedia-affiliated projects have been heavily disrupted, seemingly due to reliability issue with the infrastucture supporting the Wikimedia websites.
Is the SRE team out of office for all Sundays? How does the 10th most visited website in the world can be disrupted for so many long hours without anyone there to fix the issue?
I assume there were people working on this today, but it seems on the other hand that there is a shortage of people available for urgent needs in the site reliability engineering team.
