You're lucky to be based in JB/Johor to have found a Unifi IP range that links directly to one of CF's VPN server which is hosted at JBIX. By connecting directly to JBIX, you get to enjoy sub 10ms ping rates to SG within 1-2 hops after that which is good routing strategy.
However TM's Unifi users who are based in different regions(Northern, East Coast, Sabah/Sarawak) do not have this advantage. TM has many concentrators/edge routers spread out in different regions, probably one in every state and this is where the extra ping times is introduced especially during peak utilization season like now during festive Raya/CNY where they become overloaded with traffic.
Here is what I discovered from doing reverse tracert from Equinix/NTT/internal TM servers.
The round trip from Penang alone to JB would probably take up around 10ms-15ms.
The round trip from Cyberjaya to SG is about 10-15ms
The round trip from Sabah/Sarawak ~15-25ms
Example when a undersea cable is launched such as the ASE, it claims to achieve ~60-65ms from Changi-> Tokyo.So if I was to ping a connection from KL to Tokyo, it would roughly be 5-7ms(KL-Cyberjaya)+10-12ms(Cyberjaya-SG)+60-65ms(Changi-Tokyo)=~80-85ms
It gets even higher during peak hours/festive periods.
Different concentrators/edge routers in different regions will get different range of IP addresses for TM Unifi.
That is how they separate your IPs by location.I've read some of the users attempting to follow your advise and rebooted their modems over 10X and still not getting the 175.140.x.x range suggested is because they might not be connected to the same concentrator as you in different regions.
The reason why you might get as high as 40ms to SG even when you're so closed to the island already is because probably of TM's bad routing. It is probably making a BIG U-Turn round trip from JB-TM Cybejaya NOC-SG with different IP range getting different routing results.
Why certain Unifi users are now getting very bad connections is because the concentrators which they are now connected to are probably very CONGESTED now. They are believed to be located in northern region(Kedah/Penang/Perak) or East Coast(Kelantan/Terengganu) where all the balik kampung activities are now residing. I'm aware of this because the reverse tracert results shows that the ping rates from SG(datacentre)-Cyberjaya(NOC gateway) seem to be fine which only peaks around 10-12ms.
Acutally now CF Warp from Unifi not connect to server hosted at JBIX,it still connect to SG DC.I can confirmed that as i traceroute to any MY IP with CF Warp will add about 10ms as it goes to sg and go MY. (CF not should not have any Warp service running by JBIX)
The first picture is using warp,and check by iplocation.net
The second picture is the traceroute with Direct Unifi.
The third picture is the endpoint of the warp.(It is a anycast IP,thats why it cant be manual choose server for warp)
last picture is the debug page for showing the DC that connected by. (Warp on, COLO=SIN)




Second,normally West Unifi to West unifi normally get within 10ms,Penang or Johor is the same,all depends of the latency between your home to the local exchange center.(For example,u will see some user that speedtest to malaysia ip only get 3-5ms,but most of us get 5-10ms for the same server)
But for West to East / East to West malaysia,that really hard to say as i not sure the routing.
Third,Unifi IP normally got specific blocks for every states,but sometimes u still can get the ip that is distributed for others states(For more correct,it is distributed for different user group maybe plan?),Usually unifi would not allocate 42.X.X.X / 124.X.X.X / 118.X.X.X or 1.X.X.X for me.
But u can see 175.X.X.X 60.X.X.X 115.X.X.X can be get by most user from different states. (I think that 147.158.X.X should be the new ip range start use from TM 2-3years ago,normally allocate for Johor user if i am not wrong.- This ip got wrong geo-location at some IP database,maybe previously use by New Zealand)
And now TM seems like set the refresh timeout longer for unifi,reboot router in short time(10-20sec) will get the same ip. But if your reboot for few more times,u still can get a new ip and new subnet.(While i am testing yesterday,i need to dc and reconnect at least 5-20times in 1min to get a new ip.)
