I am flying in Business on this flight. The toilets have been inoperable for hours (not sure when it started as I was asleep). Woke up to find out this was the case.

Since then, the right side of the aircraft appears to be functioning to some extent, with just under three hours left to go, but the entire left side across all cabins are still not working. Something to do with water not reaching it but no explanation as to why.

I’m not one to complain normally but this was a self paid cash ticket and the flight is almost 14 hours long so needless to say this is far from ideal.

Has anyone experienced this before? What would cause both sides and then one side of the aircraft to have zero functioning lavatories for more than half the flight?!

Not expecting much more than a generic email response from MH if past experience is anything to go by.
