I’ve reverted the revert now I’ve increased the HDD space across all machines. It should deploy over the next 10mins. Thanks for letting me know.
That PR was actually just the straw that broke the camels back, rather than a big cause in itself. The main thing is increased usage of Exercism causing the hard-drives to fill up quicker in a day with all the solution files (the machines get reset every night). This just accelerated the issue by a couple of weeks.
