Sites up. Feeds are down.
June 22nd Update.
The L-Band feed from 98w is back up and running.
Just leave my C-Band 98w feed to go.
Making great progress restoring all the ACARS feeds.
June 18th Update.
Most feeds are now back up and running. Managed to keep the main big outage down to about 3.5 days. (Was up working on the feeds at around 3:30am after 4 hours sleep).
L-Band Americas is still down for a few more days and C-Band is still more than a month out, so those two are right as expected.
It's not you - it's me.
This is a 'planned' outage.
Additionally, please note that since the central computer storing the ACARS messages is also not receiving the feed data, all messages during this time will be lost.
If I had to guess, I'd say that the feeds will be down for about a week.
More bad news. Because a few of the satcom feeds (C-Band and L-Band) are set up via a relay computer, some feeds will not be making it to airframes.io
That said, your best bet to see ACARS messages during the outage week is to visit app.airframes.io for your ACARS tracking.
Lastly, yes, more bad news, the Inmarsat 4-F3 98w (Americas) C-Band feed will be down for at least a month. (At a wild guess). This means that both ADSC (planes plotted on tbgmap.airframes.io) and ACARS messages from aircraft to the site will be unavailable for the entire period.
The L-Band ACARS feed from that satellite will be down for 10 to 14 days. (At a guess).
We have backup L-Band feeds for most satellites, but not all of them.
With C-Band, it has been a seven-year quest to just obtain a single dish feed from the four primary Inmarsat feeds. Still no feed in sight for the 'new' 6-F1 at 84 East. My point there is that we don't have a single backup satellite dish feed for any of the C-Band data.
Here is a screenshot of just military aircraft in that area on a random day in May 2025.
All aircraft data for the site in this area will be missing from June to July 2025. |
I understand that this will frustrate many of you. I've done my best to try to keep the site and feeds running glitch-free for 7 years.
March 22nd, 2024 was the start of the worst outage with 3 months of downtime.
This is very different from that 'incident'. 2024 was not planned at all; it was a massive, sudden system failure.
I'm not going to try to retell how hard I've been working over the past two months to keep things up and running for as long as possible. Right up to the very last few minutes in fact... So yes, it would have been a LOT less stressful for me if the feeds had been down for the past two months, but I've pushed myself hard to close that gap, hopefully just to be about a week.
Restoring the feeds to the site as quickly as possible is my top priority.
Keep an eye on my X or BlueSky feeds.
The home page on the site will also have a 'feeds up' message in the 'Website News' section.
I'll also try to keep you all updated here via this blog.
My closing comment to put this data feed outage in perspective for some is to think about how much money each / any of the site users has given to gain access to global ACARS data over the past 4+ years....
We all know the answer...Zero.
airframes.io and tbg.airframes.io are run by two guys with wives, kids, and a full-time job. (And in my case, at the start of this outage, I've lost my job.)
We keep the sites going ad-free and paywall-free. We each are under a lot of pressure from family expenses and time demands. The servers the sites run on are not free of charge to Kevin and me.
Your patience and continued support are greatly appreciated at this time.
