Throughout Russia's attack on Ukraine the Internet in Ukraine has held up very well. This article shares analysis on why that is. TL;DR answer — the market is not centralized and many of the network providers manager their own egress to the broader Internet. Few centralized points of failure. This is a good thing.
Due to low market concentration at multiple levels and the relatively high number of interconnect facilities, there are no obvious chokepoints, or individual networks whose loss would have a crippling effect on the Internet in Ukraine.
The biggeest risk really is power loss. If a region loses power, the Internet infrastructure there goes dark too. And before you think wireless solves all this, remember that all wireless Internet access needs to go terestrial at some point.
This all highlights the key role that communications infrastructure plays, particularly in times of war.
