Charts not loading today

Anyone else encountering the same problem? Having problems both on MacBook Pro (macOS Tahoe, Safari and Chrome) and iPhone (native app). Both on and off wifi for the iPhone. Front pages load, quote pages (for example https://finance.yahoo.com/quote/QQQ/) load fine, but the chart is blank. And the full-page chart (https://finance.yahoo.com/chart/QQQ) is just the spinner.
