The CSSI Space Weather data has not been updated in the last few days (at ftp.agi.com/pub/DynamicEarthData/SpaceWeather-All-v1.2.txt). The last update was on June 13th, 4 days ago. As far as I know, this file is usually updated daily (it was the case for the last few months at least).
Is there any way we can know if this delay is normal, and when we can expect an update ?
You can try sending an email to support@agi.com they may be able to help you. We deal with them and they are usually responsive (although we have support contracts…)
Alternatively you can get the same data in the same format from Celestrak:
