Not sure what could have happened at 4.00am. I will investigate whether anybody left a console on standby, that could have updated itself in the background etc.

I know Sony likes to do PS4 Updates around that time.

I might be wrong and I know people will correct me if I am, but I am wondering if it was an upload, reason being pings require very little bandwidth which is why you hardly see the blue parts in the BQM due to you are mostly using the download hence the large yellow bars, but if the upload is being used up then it has to wait to be able to send a ping response, hence the blue bars.

I know I only see large blue parts when I am uploading large files like in my BQM at 12 pm which was a 2.9 GB video file to YouTube.

But like I said I might be wrong.

But yeah it could be just an update to a PC or Console that took about 30 mins to complete.

4am does look like something work up and uploading or downloaded something e.g. mobile on Wi-Fi doing backup, app updates automatically, console coming out of sleep

Otherwise no regular pattern to speak of.

You need to have a night where router has Wi-Fi turned off and no Ethernet cables plugged in.

Latency spikes when downloading are not normally caused by slowness of data, but usually by the different priorities the routers along the route apply to data and pings. As described in the FAQs and enlarged on by Paul.

When any router between you and the tbb server is busy it has more important things to do than respond to a ping, so it sends the response when it has dealt with the data, including the ACKs and on G.INP any retransmission requests. It is only if red down-spikes at the top appear that throughout questions are getting serious as that means ping packets and maybe data packets are being dropped at some point, in either direction.

Some routers are configured never to respond to pings, as you can see on many tracerts, typically shown as timeouts on all three attempts at that hop on every run of tracert on different days.

Timeouts and anomalous high response times on tracerts, where subsequent hops are low, suggest a router working very hard. A set of high times from a particular router followed by times that are never lower than that router show a bottleneck/congestion at that point. Both cases will almost always cause data slowdowns, including your gaming packets in both directions, even if no ping packets are dropped.

Looking at the live graph in my previous post, I can tell you that everybody was turned off at midnight (00:03 to be precise) and you can still see spikes. Not sure what could have happened at 4.00am. I will investigate whether anybody left a console on standby, that could have updated itself in the background etc.

Also a smart TV left on standby perhaps? I also know several people who thought when they press the power button on an iPad until it clicks and the screen blanks they had turned it off. Until they mentioned the battery life was poor and I enlightened them. They were using things like multiple weather apps updating frequently, Gmail running, even Skype not closed down.

Nothing uploading intentionally at that time, but I do have a PS4 sat in rest mode. I�ll
have a look at that, as I wasn�t aware that was the sort of time it might update. Thanks for the tip-off.

You need to have a night where router has Wi-Fi turned off and no Ethernet cables plugged in.

Difficult to achieve, but I will try to plan it.

Am I right in thinking then, that the broadband monitor will not really depict buffer bloat if it is only drawn every 100 seconds? The delays only need be a fraction of that to cause my issue, though relatively frequent.

You may have mis understood each pixel may reflect 100 seconds, but as the yellow is the maximum latency any high sample in the 100 samples in that period should show up.

So what you are trying to say, is that the monitor pings every second, and the yellow spike will be the highest of those hundred responses?

Yes

Had a look. Nothing from the PS4 last night.
