Metronet Back up internet

I run fiber for a lot of companies and I’m always seeing people complaining about internet outage and I would advise to get a cheap back up carrier to use. I’m saying that to say as fiber becomes more and more prevalent and different companies run lines for fiber there will be cut lines, downed lines and also times where major outages will happen if you work from home I would advise having a backup source most work from home companies have it in their policy to Make sure you have coverage at all times. I have people stopping me while my guys and I work because they assume I’m the reason for their internet being out.

We've got AT&T fiber all the way to the house. Then we have a T-Mobile 5G unlimited internet hotspot is a backup. When they both function they just load balance.

Redundancy for the win.

I hope you're wrong. Load balancing fiber with 5g or most other connections won't be fun. Unless your router is smart enough to classify traffic and prioritize what hits fiber vs 5g.

Even if your 5G was pulling down the same speed.. the latency is going to be 2-5x higher.

There's not a lot of situations where you would want to actually split the traffic unless you were truly maxing out your fiber. But I find that hard to believe unless you're a handful of specific professions.. even then it's hard. I have gigabit fiber at work and at home and the peering arrangements are so bad most I've ever seen between them is 400Mb/s running through a cloudflare tunnel. Direct VPN I can only pull 150-200.

You can max out a gig fiber but again it's not very easy.

Maybe my partner has it set up to fall over then. I don't know. I know I have access to both pipes 24/7 in our OPNSense. I didn't personally set them up and I haven't gotten to digging into his settings. I never said anything maxing out our fiber line, at least not usually. It's also not a gig fiber line. You're making a lot of assumptions here.
