My Computer or the Site?

[Johnny Reefer]

I've noticed frequently, lately, when I go to bring up the site, that it just doesn't come up. For a number of months it was just once a week. Usually Saturday nights, I think....? I just assumed it was a weekly site maintenance thing since Sat nights seem to be when site usage is lowest. But over the last week it's been happening alot. (Daily and then some). Might this be my computer or ISP, or is the site conducting higher than normal maintenance sessions?
Anyone else experiencing this?

Thanx much,
