Seems like it arrives with a bit more energy than a 10 on richter scale: https://www.edinformatics.com/inventions_inventors/richter_s...

No, I can’t really imagine what that means, either.

It's been tried and failed: Sun Microsystems pushed certifications in the 90s. Pass the test on some technology, get the certification. Then they studied performance. The result? More certifications implied a worse employee. The reason was the top performing employees had no time to study for the exams, but the managers of the bottom performing employees were happy to send them off to training and testing. And then the certification fad came mostly to an end.

To expand on this, if they tried to land on the water planet where time so dilated that one hour equals 7 months… what would their velocity have been when they contacted the surface? And how much energy did their spaceship need to reach escape velocity from there?

Shoot us an email at support@speedify.com. If it wasn't recently, there have been a lot of improvements at every level of the software.

Oh, I remember you! We've made major changes to the protocol since then. Connections with as much latency and loss as you had cannot be maxxed out by a single TCP connection.

We now default to a mode that uses up to 8 TCP connections in parallel on each internet connection to let us reach the full speed of connections even if they have latency and loss that limits the performance of TCP.

We'd love to get you to try it again. Email us at support@speedify.com and we'd get you a license to reevaluate.

Yes, speedify has a lot of smarts around packet loss. It uses up to 8 TCP connections in parallel to avoid slow downs based on loss.

But for the kind of burst of massive loss you describe, I'd suggest having a secondary connection it can use that during the bursts of loss. A cellular connection could be used just during these times to smooth it out.

Alex from Speedify here. It's not our project but it is exciting that they're putting our software on the router. Happy to answer any questions.

Actually Speedify on your phone is pretty good for that. If the hotspot doesn't work, it fails over to the LTE automatically so the bad hotspots never knock you offline.

Oh, yeah, sorry, I guess that's not so clear. Just install, and you start on the free tier.

We still have the 2GB per month free tier with no registration. It's available everywhere but Linux... unfortunately, without us doing anything really creepy (which we won't do), it was just too common for Linux users to trick us into endlessly starting the 2GB over. I think there was a script for automating it making the rounds on some sites.

That works, and has been done before. It can be confusing to run Speedify and the VPN client on the same box, but if there's a Speedify router box with the internet, and another box with the VPN client, it should just work.

Not at this point, sorry.

Alex from Speedify here. Yes, we make a multi-path VPN tunnel, so that calls can be shifted from one link to another without glitches (apps see the same IP address the whole time). To make this work, we do some smart things like retransmit packets that were just sent on the failed link, on the still-working link since they were likely to have been lost.

Alex from Speedify here. Yes, exactly, we have swarms of redundant servers. The servers are very reliable, but in case of failure, you're on another server in 30 seconds.

Your comment makes me realize we may need more options on what to do when the connection fails. Security-types had us add a "kill switch" to make sure traffic couldn't get out when the encrypted tunnel fails. But if you don't care about that, another option to guarantee it would go right out, would make sense too.
