SYNC Timing Synchronization failure / RCS Partial Service

[StephenEM]

Hi - seeing others post about it here, I've got regular timing sync problems, started in the last month and now a (more than) daily occurrence.  I did have an engineer booked this week, but was told 'there's a problem in the area so your engineer is cancelled' - so adding here for a record at least.  Would welcome any help and glad to share any more info.

Here's today's BQM graph  (only been running for a day or so after seeing the forum) :

And some network logs (since midnight).  I have events like this recorded since 30 December.
