Fixed internet: who builds the lines and who sells the plans
India does not have a single national wholesale network. Several operators own and operate their own last-mile fibre and backbone, while others commercialise retail plans on top of these footprints or via local partners.
- Infrastructure owners with national or multi-city fibre: Reliance Jio (JioFiber/AirFiber), Bharti Airtel (Airtel Xstream Fiber), BSNL (Bharat Fiber/FTTH).
- Large city-focused ISPs: ACT Fibernet, Hathway, You Broadband, Den Networks, Siti Networks.
- Resellers / local cable operators (LCOs): thousands of smaller ISPs sell broadband using leased backhaul and shared last-mile fibre.
Who built the network and how resilient is it?
- Long-haul and metro rings are built by Jio, Airtel, BSNL and private utilities.
- Resilience is uneven: big cities have redundant paths; smaller towns often depend on a single duct where fibre cuts are common.
- The regulator TRAI and the Department of Telecommunications (DoT) enforce service quality standards on uptime and repair time, but power failures and roadwork remain the main outage causes.
Typical fixed-line outage patterns
- Fibre cut after road digging
- Power outage at local PoP/OLT
- Backhaul congestion or upgrade work
- Router or ONT malfunction causing “connected, no internet”
Mobile networks: ownership, coverage and where issues arise
Four operators own national mobile infrastructure:
- Reliance Jio – all-4G with fast-expanding 5G coverage
- Bharti Airtel – strong footprint with 5G Plus live in major cities
- Vodafone Idea (Vi) – 4G improving, 5G limited to select metros
- BSNL – legacy 2G/3G, 4G expanding nationwide
Why mobile feels “down”
- Tower power failure → site offline until battery drains
- Backhaul fibre cut → cluster blackout
- Congestion spikes at events → slow data or call drops
- Core software upgrades → brief outages
- Administrative restrictions → temporary local shutdowns
What to do during an outage: a precise checklist
A. Home broadband (fiber/FTTH)
- Identify scope
- Test with a mobile connection. If mobile works, issue is at home or ISP.
- Try a non-HTTPS site and a speed test.
- Check equipment
- Verify LOS/OPTICAL light on ONT (red/off = fibre issue).
- Power-cycle ONT then router (unplug 60 s, restart ONT first).
B. Mobile data and voice
- Reset basics
- Toggle airplane mode 20 s, restart phone.
- Check apps
- MyJio, Airtel Thanks, Vi App, MyBSNL → network alerts.
- Cross-check
- Ask neighbours on same network; if both fail, outage confirmed.
- Contact support
- Jio 198, Airtel 198/121, Vi 198/199, BSNL 1503.
- Stay connected
- Use Wi-Fi calling, secondary SIM, or public hotspot.
Key takeaways
- Fixed broadband depends mainly on Jio, Airtel, BSNL and big city ISPs.
- Resilience is high in metros but fibre cuts remain frequent elsewhere.
- Mobile coverage is broad, yet tower power issues and backhaul cuts cause most “internet down” events.
- Use the operator apps and numbers above to confirm if it’s down today in your area and get restoration updates.
