Oh I think I know what’s going on, in fact I had allocated 894GB to this node but it’s always been rounded up to 900GB. I just noticed it shows 890GB are allocated now, so I guess the latest node software now rounds up to the closest ten instead of hundred.
And the bit of ingress I received at the beginning must be a coincidence, after some deletions probably…
I’ll keep an eye on my node but maybe everything’s fine in the end 
EDIT: I see @brightsilence already noticed that here: Changelog v1.11.1 - #28 by BrightSilence
