Bad mobile data Haywards Heath (near Victoria park).

[sunrun]

Good signal level, (4-5 bars which I take with a pinch of salt but its indicative of good)

Lots of data against SIM (>1G still available).

Get > 90% packet loss (actually its more like a handful of  packets per minute)

Is it just me?

Yes tried rebooting the phone, yes it works elsewhere, and yes tried a different device 'just in case'.

Note this is on multiple days so its not just the weather some other transient event.
