Forums still fast for me (~500ms to 1.2s loading forum pages in browser). Running uBlock Origin on Waterfox/Firefox on both desktop and mobile. Tracert giving a lot of timed out hops (to Amazon AWS/EC2 servers on the east coast, mostly Northern Virginia), though. Their health dashboard doesn't show any issues currently, but apparently the last region that did report issues was their NOVA data center(s), on the 19th (coincidentally, also the same date PoodleCorp DDoSed Pokemon Go servers). Possibly unrelated? Although there does appear to be downtime reports for Pokemon Go servers around same time yesterday, and resolving in past hour. Considering Amazon hosts a lot of servers in Virginia, a massive attack on Amazon's servers/load balancers probably could lead to collateral damage affecting AT servers, as well.
I know nothing about security and networking, though, that's just my uneducated guess. 😛
