Thanks, @emilianobonassi - the suspension of the Synthetix system would have the most risk implications from users that borrow only sUSD. For users who have other borrowed assets, liquidators benefit from the ability to pay back those borrowed assets to liquidate the position. The largest user on V2 that borrowed only sUSD has a relatively low amount of sUSD borrows ($174k), and their collateralization is relatively high (187%). Another user has supplied $687k ETH to borrow $253k sUSD and $65k USDC. As such, there is currently a relatively low borrowed amount and high collateralization. For this to present outsized risk, the sUSD borrowed would have to grow significantly.
However, a potential edge-case risk here is that the most profitable liquidation (as calculated by the liquidation bot) is to repay sUSD, and in the case where the sUSD repayment fails, the bot may not be encoded to attempt the liquidation again with another borrowed asset (thus rendering the liquidation a failure).
Gauntlet has not fully integrated with V3 yet (you may track our progress here). However, from looking at the raw data, we observed that the majority of positions on V3 are recursive stablecoin-to-stablecoin positions that do not present outsized market risk.
We will monitor the situation and continue to analyze tail risk events.
