Must admit I don’t know how many are interested in the topic of automotive Ethernet here, but I guess I won’t know if I don’t try?

We’re closing in on Automotive Ethernet Congress 2026, as always in Munich, 24-26th of March!

If you’re attending, me and my colleagues Iago Alvarez and Lars Völker from Technica Engineering, and Max Turner of Ethernovia, are hosting a training on TSN, SOME/IP and MACsec the day ahead of the main conference.

As we’re on the topic of type faces as of last weeks, did you see https://youtu.be/Y3mbS6AqmCA?si=mIksqH5vwscw41fg @gruber? (Article about it up at https://www.dezeen.com/2025/12/19/volvo-centum-typeface-safety/ as well)

@BucciaBuccia @gruber I’m not nearly as into the details on the IDS itself, but yes that would be a very effective way of taking out for an entire country. It does seem (and here I flag for that I’m uncertain about reliability of the source) like parts of IDS is queryable through APNs directly though: https://theapplewiki.com/wiki/Identity_Services

@gruber I also think this is changing, as there so many messaging services these days that it’s hard to implement filtering rules. Last flight, two weeks ago, at least Lufthansa had changed to let their ”messaging” tier be severely bandwidth capped (I think it was 50kbps) instead.
@gruber I’ve always gotten all push notifications, even from services where I can’t reach the services itself for the remainder of the flight.

@gruber ahh, just when I didn’t think I would find any official documentation: https://support.apple.com/guide/security/secd9764312f/web

Here it states in the opening section that iMessage is delivered through the push notification service.

iMessage security overview

In iMessage, Apple messages and attachments are protected by end-to-end encryption so no one but the sender and receiver can access them.

@gruber Aeroplane wifi thing is still true for sure, brining some validity. I can’t remember where I saw the initial documentation on this, but the closest thing to it I managed to find today is this: https://support.gfi.com/article/107782-when-blocking-imessage-push-notifications-are-blocked

@gruber This is also why on flights, when you have ”messaging only” service, you are still getting the push notifications.

@gruber About iMessage, isn’t it still that the iMessage traffic is merged on the same endpoint as the push notifications? So, if taking out iMessage all remote push notifications to iPhone would immediately cease to work.

This is how they shoehorned in iMessage under the nose of all phone operators, who already had been using the push notifications as one of the the major reasons for their customers to get a iPhone, and now they couldn’t block the iMessage traffic.
