The server IPs are hard-coded into the Telegram client's source:

https://github.com/DrKLO/Telegram/blob/d7deedfa33ddfa51c72a5...

You know you can just run

$ git clone https://github.com/DrKLO/Telegram.git && cd Telegram && FILE="TMessagesProj/jni/tgnet/ConnectionsManager.cpp" && git log --reverse --format='%ad %h %s' --date=short -S'149.154.175.50' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'2001:b28:f23d:f001:0000:0000:0000:000a' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'149.154.167.51' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'95.161.76.100' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'2001:67c:4e8:f002:0000:0000:0000:000a' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'149.154.175.100' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'2001:b28:f23d:f003:0000:0000:0000:000a' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'149.154.167.91' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'2001:67c:4e8:f004:0000:0000:0000:000a' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'149.154.171.5' -- "$FILE" | head -n 1 && git log --reverse --format='%ad %h %s' --date=short -S'2001:b28:f23f:f005:0000:0000:0000:000a' -- "$FILE" | head -n 1

To get when the IPs first appeared, right? :D

They've been the same IP addresses for ELEVEN years, and they precede the article you linked by THREE YEARS.

They're not playing the catch-up with Russian government. Either Russian government is completely incompetent in that they're blocking 3,000,000 IP addresses and failing, or they are LYING about attempting to block it, which would indicate Telegram is a Russian op.
