First post here, just about to join AAISP tomorrow so this post caught my eye.
Leaving Aquiss/CityFibre for AAISP after issues with congestion on working days that starts a few minutes before 9am. CityFibre didn't really take much interest and closed the ticket on Aquiss as no fault found. The TTB BQM was really helpful in seeing the issue graphically.
What I noticed was that using f8lure.mouselike.org as a second opinion, which also sets up a chart from a Firebrick at AAISP (so you get 2 for 1), didn't always mirror the chart of TTB. Usually the AAISP chart showed no congestion issues, even though TTB and f8lure did. Just recently the AAISP chart is showing the same pattern of congestion, when sometimes TTB or f8lure are not showing, but whichever chart is showing congestion it always kicks in from a bit before 9am getting worse over the course of 10 or 15 minutes and continues, can be most of the working day or just really bad for an hour before recovering mid-morning, so seems to me several routings that CityFibre have me taking are all running close to capacity and easily get very congested with business traffic.
Whilst it might sound like I'm obsessing over the charts, I'm not, the issue is seen as generally slower speeds (at worse from 900Meg down to around 10Meg) and less than great video calls, just backed up graphically by the monitoring.
So a bit disappointing to read that AAISP with TTB monitoring there seems to be some issues with some packets taking longer as reported here. I'd recommend the OP sets up a second opinion via f8lure to see if it is a wider problem or just a routing issue to the Thinkbroadband network. When I switch over I will report back with my BQMs for comparison.
This is a normal day on Aquiss/CityFibre, being today, although it gets a bit rougher on the chart from 9am nothing that causes a problem:
What happens on a bad day, CityFibre business traffic presumably. I've never known congestion at 9am in the morning with any ISP ever until now, 9pm maybe
