Often an easily resolved upstream noise or power issue. Go back to the status page where you got those two entries from, and copy and paste in the same way all of the Network log, and then in separate posts the contents of the two other tabs titled Downstream and Upstream, and we can have a gander for obvious problems.

If it was rebooted yesterday then you definitely have some noise on the line which would require further investigation. VM staff should check this post eventually and confirm the diagnosis and maybe even book an engineer for you (unless it's a area-wide issue, have you checked for known network faults?)
