I've been noticing my accounts going offline and back on during the day for almost a week now. Sometimes for most of the day. Very frustrating. My accounts will not show that they are down, but none of my keywords will trigger ads at all.
Do most of you do actual searches of your adwords during the day? If so, how often?
Not sure I'm reading that right, but do you mean that you search for phrases you're targeting and don't see your ads at times? I'm not sure how to interpret that "none of my keywords will trigger ads at all."
Assuming that is what you mean, it's not evidence that your account is "going offline and back on." More likely it's just that the terms are searched often enough that your set budget/CTR don't allow your ads to be placed every time someone does the search.
