Plane Wi-Fi isn't slow because of bandwidth. It's slow because of round trips to a satellite 36,000 km up.

satmux fixes the part that's fixable:
- Pages that timed out on cabin Wi-Fi load in 2 to 5 seconds
- Tested on a real flight: 3.6x faster, 0 failed loads instead of 3 out of 6
- Fixes GitHub, npm and pip timeouts mid-flight
- It works through the Wi-Fi you paid for and doesn't bypass the login page

Needs a cheap cloud server near the satellite ground station, for a few cents an hour.

If you send email from your own domain, some of it stopped arriving on Nov 5.

Outlook, Hotmail, Live and MSN started quietly rejecting mail from domains with no DMARC record. Small senders too. Microsoft never announced it.

Only some messages bounce, so you'd never notice. Invoices, replies and confirmations just never show up.

Check yours in 5 seconds:
dig +short TXT _dmarc.yourdomain.com

No output means you're affected.

The fix is one DNS record:
Name: _dmarc
Value: v=DMARC1; p=none

It changes nothing about how Gmail or anyone else treats your mail.
