Hello.
There are some changes with SIM cards in Russia. As I noticed in Holafly it’s not possible to get eSIM card in Russia. I’m planing on my next trip to Russia so maybe you have different options to solve this issue. I’ve been using Holafly so far in Russia, so I hope that there already alternatives.
Yes, it seems ALL the eSIMs are shut down now. I have just tried Holafly, Nomad, Mobimatter & eSIM.sm but all “are having problems”. So, are there any alternatives left? I will be travelling to StP in 2 weeks so I can see if I can find an eSIM before then.
It looks like the Matrix eSIM from India needs an Indian phone number to buy it 
Meant it for the information that it provided on dealing with the blackout - not recommending the esim that they provide.
