[tor-relays] Very unbalanced in/out connection ratio

Hello, I've been running a middle relay [1] for months and I have always noticed an unbalance between incoming and outgoing connections (monitored through arm). The incoming connections were always in between 0-10% more than the outgoing ones. This morning though the unbalance has reached so far unseen levels: arm reports more than 2500 incoming connections while outgoing are little more than 200. Is this normal and, if so, why? Thank you, Mattia [1] https://globe.torproject.org/#/relay/0D14A4498E7D1854696CC07548653EA4CD3CB2D...
