The overall Network Up And Download Speeds

Did the overall network uploads and downloads get worse for anyone else after the 'improvements', that started on I think Thursday or Wednesday prior to this post, concluded? Did they even conclude? I'm confused, because I swear my speeds have greatly diminished. They were awesome prior to these... 'improvements'. The network checker is telling me that 'their system hasn't reported any network issues.'.

Before I was getting I think around 70 to 100mbps download or something like that, and around 15 to 17mbps uploads or maybe 20. The uploads seem to be around that area again, but the downloads, they're at like, 5-20mbps now.

Not sure if it's something on my end, or if I'm not alone in this. Things seem unusual at the moment.
