Insane ping spikes for me on EUW

My average ping has been 48 for a very long time, even before the lag spikes started happening for me I was averaging 48 ping but now sometimes out of nowhere and really quickly my ping will climb to 400+ and usually takes about 2 minutes to slowly climb back down to 48. Why is this happening to me ? I am using SKY broadband for my internet. Is anyone else having this problem ? {{sticker:slayer-jinx-unamused}}
