After looking at Varnish VCL with Adam, we discovered a bug in regex resulting in many phones being detected as WAP when they shouldn't be. Since the older change[1] simplifying detection had also fixed this bug, Brandon Black deployed it and since today the usage share of WAP should seriously drop. We will be monitoring the situation and revisit the issue of WAP popularity once we have enough data.

Thanks. 7-9% of responses on Wikipedia Zero being WAP is pretty substantial.

These zero.tsv.log* files to which I refer seem to be, basically Varnish log lines that correspond to Wikipedia Zero-targeted traffic.
Yup! Correct. zero.tsv.log* files are captured unsampled and based on the presence of a "zero=" tag in the X-Analytics header:

Do I understand correctly that field as Content-Type?
Yup again! The varnishncsa format string that is currently being beamed at udp2log is here:
