Mine is fine or not noticably slower but some people elsewhere complained recently about problems with XL and data packages?
Maybe your internet provider is slow or a cable is down or more people drawing from the main server or whatever they call it., perhaps a new apartment block just got connected to your downstream thingy hence you lost a mps or 2 or something
Or could be the rain? Cyber Friday?
Or yeh, maybe your cache.
Ok I don't know. Have you tried turning it off and on again?
lol
