Unusual spike in latency

Hi there,
On BT Infinity 20-24 Mb down 1Mb up and got this unusual spike in latency tonight,
what are your opinions on this problem? line fault e.g noise, gateway problems, or congestion somewhere?

Thanks.

Looks very much like congestion on the network , could be at the exchange, or anywhere within the core network it's self including the isp's peering resources, the time backs up the congestion theory (Peak) There have been several others reporting problem's but i haven't seen an infinity BQM showing the problem as significant as yours, but that could well indicate that it's near to you, help others to Id where abouts what exchange are you on ?

Im on this exchange
on cabinet 3, its happened before but not as significant as that, and around the same time.
I am very curious :/
