This must be nothing but an energy saving exercise. As there will be less people using the Three network late at night, some servers are being put to sleep. This obviously lowers Three's electricity bills.
Every single night I watch the light from my broadband box go from blue to green at exactly 1:02 am (although the past few nights it has been around 3:00 am). When my broadband box has a green light, packet data is being lost in transmission, when the box has a blue light, I have no issues.
7:00am on the dot, the light on my box goes from green back to blue. This cannot be a coincidence, it has done this every night since I purchased it in December. I'm surprised Three can get away with this but I suppose that it is a trick of their trade only to maximise their profits, and lowkey all other mobile networks are probably doing the same thing.
I cannot tell you how frustrating this is for someone who works nights. I have considered cancelling numerous times as I am usually better off using the hotspot on my mobile device which doesn't even have 5G (iPhone 11 on O2 network). It seems to work fine in the day, achieving download speeds of 300+ mbps and latencies as low as 25ms, which is the only reason why I have kept it. I highly doubt that Three will even address this, at the end of the day they are a business and will do anything they can get away with to save a few pennies. Most people are uneducated on the way that networks work, this is only to their advantage.
