Yep. I pay 1700 rupees for the 160 Mbps plan. I am currently getting the same speed you mentioned with the usual packet loss and connection cut every couple hours. Hopefully atleast some sort of relaxation would be given on the lockdown on 17th so they can provide me the connection. Atleast hopefully will be able to join minecraft servers from then...I get a dynamic public IPv4 with all ports open. But external ICMP requests are blocked, which means no Hurricane Electric IPv6 tunnelling, if you're into that.
I don't play a lot of games, so can't really help you with that. The last time I played something, it was pubg lite for desktop. I remember getting a ping of 50ms - 60ms. Atleast that's what it was showing on the bottom right corner of the screen, during gameplay.
My lockdown experience was atleast better than that of my friends, when it comes to internet performance. During the early days of lockdown (March end to beginning of April), there was some congestion, which obviously led to lower speeds, but nothing noticable, unless you perform a speedtest. There was no packet loss at any stage. My 100mbps speeds became 60mbps, but only during lockdown peak hours (10am to 10pm). Then it would gradually increase back to normal after midnight. Then again the same thing next day. I complained about this to hfiber, and they acknowledged that it was indeed a network congestion. They assured me that they'll increase their upstream capacity or something like that.
A week later, the congestion issue suddenly disappeared. I tried to contact them, but their office was totally closed due to lockdown.
But atleast I didn't face any serious issue. Most of my friends are on alliance, and they all faced the same issue of network congestion during the first few weeks of lockdown. But the most bitter experience that one of my friend had was with SiTi. They intentionally throttled everyone's account down to 20/30 mbps, to prevent congestion. Atleast that's what his LCO told him. Sucks to be a SiTi user.
No, they don't turn off anything during thunderstorms or rain. Its a pure FTTx network, and hence has got nothing to do with thunderstorms. However, you'll lose connectivity if there's a fiber-cut in some area. This rarely happens.
About the pm thing, I'm also not sure how a user can connect with another on this forum. Maybe there's some other way of communicating with each other.
