Thanks. Yes, I did see there was a Black Swan on BTS and they had a chain freeze which I suspected was related. So SBD is not the only peg mechanism that is having trouble and at least with SBD it remains liquid and trade-able despite the haircut.

I tried looking up CarbonUSD that you wrote about earlier. For now I've parked some funds in TrueUSD which in an ERC20 token that I could at least store in my cold wallet.
