I hope this is the right place for this type of question.
Around 7 or 8pm (Japan time) my site will hang or time out when accessed about 75% of the time. 25% of the time, it responds normally. This issue always happens around the same time.
Server stats show no real increase in traffic. Server logs show no strange users interacting with the site.
Any advice on what might be happening and how I can begin to deal with it?
