portal become sudently neutral

in Report a Bug
A portal in my possession was attacked " Fresque littoral, 63 rue montechristo 13004, Marseille " , I was charging it in live to prevent it destruction from the opposite side ! But for no reason the portal became sudently neutral ! And few second after, the guy name " wizardofoz85 " put it own resonators.
It was not a Jarvis virus. How could an attack sudently let a portal became neutral ! It is the second time I see this !

A portal usually doesn't become suddenly neutral. Based on your description It got attacked and destroyed
I'm thinking you just don't see the attacks because either the server doesn't pass them soon enough or your client doesn't receive on time.
Charging a portal to prevent destruction is basically impossible anyway, especially if there are no mods left to defend it. The game is just to slow in updating the portal status.
If a portal would turn neutral without attacks and fully charged, that would be an interesting case though.
Major lag is a currently reported, bug
Secondary to this is the terrible way, ingress sends alerts,
Networking/environmental conditions and I'm guessing priority updates, mean its possible for clients to receive portal status, updates before resonator health
