    I have a redundant 2 ISP setup, and use multipath TCP to use both of them at the same time. A very outdated post about my setup : https://www.sajalkayan.com/post/fun-with-mptcp.html I now have 2 broadband ISPs, and optionally I can hook in my phone's 4g into the mix. Multipath TCP allows me to "mix" bandwidth of both ISPs at the same time.

    See here: https://twitter.com/search?q=from%3Aarchiveis%20cloudflare&s... Archive.is intentionally returns bad results to Cloudflare DNS, because Cloudflare don't send them the EDNS Client Subnet Header. Archive.is haven't said much about why, but what they have said appears to accord with this blog post: https://www.sajalkayan.com/post/cloudflare-1dot1dot1dot1.htm...

    Another way for "bonding" would be to use mptcp ( http://multipath-tcp.org ). You might need to patch and build openwrt yourself for it... The key difference is with mptcp each individual tcp connection uses both connections at the same time, rather than picking a lottery. I blogged about my setup at http://www.sajalkayan.com/post/fun-with-mptcp.html
