Yup, they changed all sectors on LHR-CGK overnight to AMS-CGK & vv
Expect mass panic and inability to reach any of their call centres for the next 5 days.
Interesting in above - I have no idea why people think they would get rerouted on EVA Air?
The fact they are explicitly allowing rebooking on:
3.1.KLM (route AMS-LHR vv.)
3.2.SQ (route SIN-LHR vv.)
3.3.CX/KA (route HKG-LHR vv.)
is incredible - but note for they are allowing rebooking only on cheaper classes (i.e. SQ in D) so I expect some issues over Xmas/NY where SQ/CX will be busy.
