Very sorry to hear that. But thanks very much for your contributions!

Just out of interest... Did you try experimenting with the "Factory Reset" option when you were given sub-optimal GPUs?

I had consistently been getting two 24-hour sessions each day with no worse than two P100 cards, and occasionally two V100s. Sometimes T4s were in the mix. Tonight when I started the next day's sessions I got K80s. That's unacceptable for this premium price, so I killed the two sessions and I have to say goodbye to Colab again. It was a good three week run.
I think you need to restart sessions completely after upgrading, and maybe it takes a little bit of time as well.

I was starting to get mostly T4's with occasional P100 on Pro nonplus(sed), and then I upgraded to Pro+ I immediately got 2x T4s again on Pro+. But the next day and since then, I have been getting V100's and a few P100, so I think I should have reset those 2x T4s sessions completely that first night and restarted, or maybe it just takes a day for it to update.

Even though it seems like a hard blow from $10 to $50 per month, I do think it is just a case of us being used to "too good to be true" until now. Last year when I started on normal Pro I was running 3 sessions P100 for 20-24 hours a day for $10 per months, so 1800-2160 hours of P100 for $10. Then later you could "only" get 2 sessions for 20+ hours or 3 sessions for much shorter but instead you could get V100s as well.

$50 isn't even enough to cover the power cost if I run 2 sessions P100/V100 for 20-24 hours per day, so 1200-1440 hours per months or 3.5-4.2 cents/hour.

Yes; I "factory reset" twice on each of the two sessions receiving K80s, and was given another K80 each time.

I figured I was saving about $20/month electricity not running my own 1080ti GPU, and also not having the additional heat load in the room. Also the elimination of fan noise was worth something to me.

The graph from Challsall's site gives a good visual of the work I accomplished in three weeks of Pro+ (the blue to the right side).
