What may cause these performance brakes?
I don't know much about servers and their performance but it seems from these graphs that my server was simply not working after 3:00am, 13:00pm and 17:00pm for about 20 minutes. What may be the cause of that? I have more than 2000 pagieviews during the day so there is always someone visiting the site. Although, I don't monitor my server performance all the time, once a week maybe, but I haven't seen this before. Any help? Or should I contact the support team? Thanks to everyone.
