"Intermittent" is a good way to typify the last couple of days. Hours will pass, and all will be good. Then, suddenly the log-outs, and horrendous slowness will creep in. To read just one post, I had to log-in twice, and to post, three log-ins were required. Then, things snapped back to "normal."
At least over the last two days, "normal" has been, well "the norm," and the issues seem to come in clusters, but they appear to be getting farther apart.
