Latency and packet loss. Possible traffic issue?

[Mills78]

Good afternoon,

Up until Thursday (around 3.30pm) I have had no issues with download speed, packet loss or latency. However, since Thursday (writing this on a Sunday) I have had the same issue from around 3.30pm until just past midnight (although it started at 11.30 am today). Now, in that time window, I get around 10mb download, 20 upload (usually somewhere between 200/230mb download, and 20 upload, and constant packet loss, with a jump in minimum latency. I will attach the BQM for reference. BQM have some example graphs, and the one they have that is similar supports an issue the ISP end  possibly a traffic issue? 

Any help would be very much appreciated.

I'm in the Bromley area as well. Perhaps it's something affecting some parts of the south-east currently? Either way, hopefully it's resolved soon.

Hi @Mills78,

Thank you for your posts and welcome to our community forums. We're here to help.
 

I am so sorry to hear that you're having some issues with your services recently. I checked the BQM that you provided earlier in this thread, and there doesn't appear to be anything appearing there that would be of concern and causing the issues that you've explained you're experiencing.

Are these problems ongoing for you today? If they are, can you check our Service Status page to see if there are any known area impacting faults being reported that may be affecting you? This is updated regularly if a fault is detected and being worked on.

If nothing is being reported there, please let us know what diagnostics and troubleshooting you've carried out thus far and we can proceed from there.

Thanks,

Afternoon Zach,

Since around 2.30pm on Monday the issue seems to have been resolved. If you look at the BQM for then it was starting to get bad again, then instantly reverted back to normal. So far so good.
