Hello,
After completing a second screen of my app (mostly copied from another existing screen through the backpack) I tried to compile and build the app (both QR code and APK options).
However the following message comes up: “The build server is currently busy. Please try again in a few minutes.”
Is that really a server issue with the build feature or could be that my app is too large? I have tried to refresh the browser but nothing yet. Any ideas?
Thanks!
I’m having this problem now too. Is a bug?
Could someone help us?
att
Same with me
I don’t know what to do…
We’re experiencing some disk performance issues on the virtual machines running the build servers. We are looking into it.
i have a same problem
We are aware of the problem. The storage system that provides the backend of the buildservers is broken. If the problem persists, I will move them elsewhere. Btw. this site is also on the bad storage system, so it may go down 
Every time i try to get a qr code it says that the server is busy. it has sayed this for the past 10 min. Please help!
Even I’m also facing the same issue when trying to build the app it is saying server error and getting all the time server is busy try after some time.
May have had a blip a few minutes ago, but seems to be building OK now…
@JayIM the main build server is working (though at times it is a little slow) at the moment due to heavy developer usage most probably.
Advice is to “Please try again in a few minutes”; that usually works but often not immediately.
In the meanwhile, you might use the alternate server ( http:// code.appinventor.mit.edu ) if you need immediate access (you will have to import your Project aia).
Can you build your Project now?
Facing this error , Like after 4 to 5 times it starts compiling the project , which takes a long time , and sometimes again the message appears
The build server is currently busy. Please try again in a few minutes.
compiling projects didn't take so long before.
Thanks for help
Yes, nearly all the build servers are currently running at capacity at this time. Try again later, this is the peak period.
I am also facing this problem.
Try later, the servers are very busy...
But why this problem happens?
Because:
MIT monitor server capacity, and if demand continues to exceed supply they will consider adding more build servers. (they have only recently added three more build servers) As I have said, this is a peak period for developers building their apps, putting the servers under load, causing the message you are receiving. Try again a bit later.
Would any one (@jis ?) object if I post my app to scrape and summarize the build server summary here?
Here is five minutes of the MIT Build Servers today as of a few minutes ago (11:52 am CDST). Usage is heavy but not severe at this moment. Occasionally, I have seen average usage for short periods of time around 7.
When the notice Please try again in a few minutes appears, things are very busy; try again. Notice there are peaks and troughs to activity. If you attempt to build during a trough, you are more than likely to succeed; unfortunately no one can predict when a trough will appear.
The maximum builds possible on each server is 8 (red marked row); the number of builds simultaneously taking place on individual servers (green marked row) in the bank of 15 servers varies with the load//number of developers using App Inventor 2 to build their apps.
If you can't build; wait a while and you will be able to finish your app. You are sharing the build servers with lots of developers.
As Tim mentioned, MIT recently added 3 servers to mitigate issues. Evan recently indicated "Peak usage is typically around between 9am and 11am US Eastern time"
I would prefer to see a:
current number of builds / total build capacity %
webpage we could click on - or show this on the build servers busy message....
