I spend a few months a year in Mumbai, India.

I have a truly unlimited 300Mbps fiber connection as the primary source ($25/Mo), a second 100 Mbps connection from a different company as backup ($10/Mo) and my mobile LTE as the third backup ($10/Mo). AND my international roaming US Google Fi network as the 4th backup for $10/GB :)

This setup does work pretty well for me.The backups have come in handy at times.

My mom had slow DSL for years 6Mbps/1Mbps through the local phone company. They had stopped offering DSL to new customers for years.

I had to stay with her one summer while we were literally between places to stay. Our lease was up and our house was being built.

She got cable internet so I could work. She now has Had both DSL and cable for four years just so she will have backup internet and if she cancels the DSL she won’t be able to get it back.

4 days is pretty good turn around time for most US cities that aren't NY or SF.

My work is entirely online. I haven't worried about not having internet for a while.

I don't live in India, but if it happened in an individual building that sounds like perhaps this was due to management of that building and was just an isolated incident.

So, it's most likely that the cable got damaged due to bad weather (rainy season, laying out cable open to the sky), or the closest switch suffered a damage due to electricity fluctuations. These are the 2 main reasons for internet going down for that long. With me, it usually happens during a power cut. While I have UPS power backup and my router keeps running, it seems the local (geographical) area hub doesn't and internet goes down for 5 minutes.

I meant minutes.

Is it "travel" if you walk 30 metres? :)
