Thanks jbrennand,
I have contacted VM again via chat and they made me reset the hub + they did a few refreshes on it saying everything looks fine. Everything was fine this afternoon but when I tested again around 7:30/8 pm I got the same lag spikes, even though less than before.
I'm trying to understand what's the cause of this if it could be over-utilisation in the area during peak times but it doesn't look like it from the BQM right?
I'd like to have another engineer take a look at the mess in the cabinet, only because the first engineer said it might be that and he saw there was something wrong in there.
Thanks
