One thing I can recommend that makes scripting in python with external commands a lot easier is the `sh` module:

https://pypi.org/project/sh/

Basically you can just `from sh import [command]` and then have an installed binary command available as function

  from sh import ifconfig
  print(ifconfig("eth0"))

Thanks, that was of great help!

Just for reference, the ping command is a little different

  sudo ping6 -D -G 1500,1400 fly.io

I set an MSS to 1492 which pfsense (my router) translates to an MSS clamp of 1492-60 for IPv6 and 1492-40 for IPv4. This is a German Deutsche Telekom Fiber connection. Now everything works fine, I can request fly.io (and also discovered that https://ipv6-test.com was not working before and now does with the MSS clamping)

Does MSS clamping have any disadvantages? Are there any alternatives in my case?

How could I find out if this is the case? And, what can I do about it? Disabling IPv6 obviously fixes it, but that it not a solution...

Does anyone else bump into the issue, that the fly.io website does not load if requested via IPv6 on Mac? I tried Safari, Chrome and curl and neither work:

  $ curl -v https://fly.io/blog/introducing-litefs/
  *   Trying 2a09:8280:1::a:791:443...
  * Connected to fly.io (2a09:8280:1::a:791) port 443 (#0)
  * ALPN, offering h2
  * ALPN, offering http/1.1
  * successfully set certificate verify locations:

  *  CApath: none
  * (304) (OUT), TLS handshake, Client hello (1):
  curl: (35) error:02FFF036:system library:func(4095):Connection reset by peer

Requesting via ipv4 works

Just to check: Could it be that pihole (dnsmasq) has an issue with these dotless domains?

I'm getting a NXDOMAIN for `dig ai.`, but when directly doing with an upstream server (i.e. 8.8.8.8 or 1.1.1.1) it perfectly works.

I assume this is the result of the `Never forward non-FQDN A and AAAA queries` setting being checked in pi-hole (which is AFAIK the default).

As the numbers are absolute, these maps are basically influenced by population densities.

Also search for City names which yields very suspicious results: https://www.kartezumnamen.eu/en/index.php?sur=Hamburg&s=Sear... https://www.kartezumnamen.eu/en/index.php?sur=Berlin&s=Searc... https://www.kartezumnamen.eu/en/index.php?sur=M%FCnchen&s=Se...

I don't think there are that many people called like cities and also they don't all live in those cities.

I tried to deploy an application I currently have running on Digital Ocean App Platform (their Heroku competitor) also on fly.io. The app is using Python/Django and Postgres, ideal to test.

I must say the deployment experience was great, stuff just worked, brilliant.

One question in case someone tried that: How can you customize the postgres config? I want to enable pg_stat_statements, and one needs to add `shared_preload_libraries = 'pg_stat_statements'` to the config for this. One could also make this the default maybe? It is the default on most cloud providers (AWS RDS, Digital Ocean).

Great news!

Just for reference: The latest release for Django Rest Framework is not compatible with Django 4.0 yet. At least my first attempts failed due to a missing `pytz` dependency. This is fixed in the `master` of DRF on Github. Installing `pytz` explicitly again to your project fixes DRF for now.
