We find about 1.6% of incoming traffic to be identified as Internet Explorer UNKNOWN.
The UA strings lookslike these:
select p.useragent, count(*) as cnt, count(distinct user_id)
from php_logs p
join woothee_useragent_dim w
on p.useragent = w.useragent
where dt >= '20150401' and dt <= '20150430'
and name = 'Internet Explorer' and version = 'UNKNOWN'
group by p.useragent
order by cnt desc
limit 30;
