Ever since moving house and hooking up with big pipe I've been getting random slow downs and today's has been the worst yet.

It happens on all devices wired and wireless, its not the same time of day, and its not weather.

Usually I notice a webpage being crazy slow, at this point I run a tracert and see some real slow hops (200-500ms for the hops to global-gateway) but it usually completes, and after about 5 minutes we're normally back in business. Sometimes I reset the router and its fine after but I suspect this is coincidence as when I don't reset its fine also.

Today the tracert and ping where timing out completely one time I got a 2000ms hop to global-gateway, I restarted the router and after I was still getting the same problems. Go do something else for a while and after its just fine again.

Using a Telecom HG630b with line stats below, any help appreciated.

Are you torrenting and/or saturating your upstream at the time?

sbiddle: Are you torrenting and/or saturating your upstream at the time?

Whilst I cant completely rule that out, normally there is only one laptop and two phones connected.
Never any torrents, no signs of any OS updates at that time for any of the devices.

From experience this is often caused by the saturation of the 1meg uplink on an ADSL. It is really really easy to flat line the uplink for long periods of time with a simple Dropbox/Google Drive sync and it sits in the background without you knowing you are doing it. Its a shame Chorus DSLAM's don't support Annex-M as this significantly helps.

Guess I need to have a closer look at that next time, but nothing has been setup for auto-uploads to my knowledge.
Thanks for the tips.

we didn't see any unusual spike in traffic on monday, and we're nowhere near our capacity.

If you are getting a slowdown at peak times it's probably either:

1) local to your exchange/cabinet (unlikely, but possible)
2) local to your property i.e. flatmates uploading, wifi congested.

I occasionally get this experience, and find that my IP changes several times in 12 hours. Normally the IP doesn't change for 10+ days.
Perhaps you are getting the same scenario, and this causes or presents the experience of slowdowns.
