Inaccessible pages

For about a month now, I keep landing on the Ошибка: не удалось открыть страницу page, whatever publisher (Springer, Elsevier, De Gruyter, etc.) I try.

I’ve tried []( / []( / []( either on Tor and on the usual browsers but to no avail.

Does anyone have the same problem ? It seems as if sci-hub were ok but there were no proxy available, but this has been lasting for a long time now.
