Huge spike in consumption

Just posting here in case anybody has seen similar behaviour in. their app(s). For apparently zero reason (i.e. no uptick in live user sessions, page views or background processing) we have seen a large spike in capacity (legacy plan) that has surged us over 100% twice in the past hour. The driver for this is a range of frontend data searches that normally contribute minimal consumption but seem to suddenly be weighting very heavily in the mix. Anybody else seeing similar behaviour?
