Lag spikes recently

[#1]

Hi,
In the last few days we've been having issues with lag spikes and timed out requests. Is there anything going on that we should be aware of?
Not sure what information you'll need from me. Here's a bit of ping:

Hi there,
Is this happening with anything in particular that you're trying to connect to or just an issue in general.
If its the former performing a "pathping" would provide some useful results.
Also how's the speed of your connection doing?
