Where are those 70 machines? And we cannot forget the need for trained folks to service them.
That 35 EUV machines in Taiwan and 70 EUV machines global is from an article of May last year in the Dutch FD (very reliable source) referring to the status of the year before (2020 !).
My bad that I remembered that as "currently". It wasa an article on greening the energy consumption of making wafers (approx 10 kWh per wafer)

Digging in to trace where the others are:
From an article of the Korea Economic Daily of March 2021:
https://www.kedglobal.com/foundry-competition/newsView/ked202103150012
ASML has increased the production of EUV scanners and produced 75 machines since 2018 when demand from clients for the 5-nanometer process chipsets was increasing. TSMC is said to have bought some 60% of the machines produced.
This would mean Taiwan has in 2021 45 of the in total 75 EUV machines.
According to industry officials, Samsung currently has 25 EUV scanners, about half the quantity owned by its bigger rival TSMC.
So we have now for 2021 45 in Taiwan and 25 in Korea.
That article also stating that max production capacity of ASML is 40 EUV machines per year
(note from me: ASML is in the process to increase capacity with 50% more on the shortest term possible, hindered by practical issues of some of the critical suppliers (in total 5,000 suppliers globally) => special teams of ASML doing interim management there and all that)
=> 5 EUV machines still missing for 2021 status.
Where ? IDK
AFAIK it is not Intel because they skipped the EUV generation and go straight to the high-NA 3 nm generation
(Intel strategic partrner by now with ASML and just announced a giga chip factory for Germany (Magdeburg) and the US).
And AFAIK also not the Korean chip manufacturer SK Hynix.
https://wccftech.com/sk-hynix-chief-replies-to-reports-of-sending-euv-chip-machines-to-china/
Korean memory manufacturer SK Hynix's chief executive officer (CEO) Mr. Lee Seok-hee outlined that his company will "wisely" navigate the ongoing tensions between the United States and China when it comes to installing cutting edge chip manufacturing equipment in its Chinese facilities. SK Hynix, which is one of the world's largest memory module manufacturers, is currently upgrading its plants with machines that are capable of using extreme ultraviolet light to print semiconductors. These machines are regulated by the U.S. government who has prevented their manufacturer from shipping them to China due to fears that they might e used to build products for the Chinese military.
EDIT: perhaps not clear to outsiders, but SK Hynix has 50% of its memory chip production in Wuxi, China, and wanted to increase capacity there with EUV.
On that servicing... what do you mean ?
