I changed my TT package just before Christmas but kept fibre large. I was enjoying speeds of 48mb but this has now dropped to 38mb. Please check and confirm that I have not been downgraded to medium by mistake. Doing a speed check I get a ruler flat 37.6mb which looks like it's being throttled.
If I am still on large please look into why my speed has dropped nearly 20%.
Thanks,
HB
