Yeah this During lockdown here in Italy one day we started getting calls about performance issues performance degradation, vpns dropping or becoming unusable, and general randomness of this isn't working like it used to. All the lines checked out, no bandwidth contention etc only strange thing we found was all affected sessions had a lot of OOR packets with a particular network in Italy. With them we traced it down to traffic flowing through one IXP and found they had added capacity between two switches and it had been configured with per packet balancing. It was changed to flow based balancing and everything went back to normal. Brian
