Yes, I would want to take all the way back up and reanneal. Unless you peeked, it's hard to say when that paperweight broke, on the way up or down, but I'm guessing up. If you only went up to 800* on a fast ramp, then you've introduced stress into everything else, just maybe not enough to break right now.

If I'm taking medium stuff back up I'm usually on a 200* ramp to anneal, then run the program per usual once I'm done. If it's real thick then a 150* ramp. Glass is fairly forgiving on the way up, just maybe not 950* an hour forgiving.
