Down in Singapore and Australia but not in Europe or North America, from what I can see.

Agreed.

Australia reporting errors: https://downdetector.com.au/status/wikipedia/

Not just you. Tested from various worldwide locations, 503 or timeout everywhere.

Back up now.

Fine in Winnipeg, MB as well as Vancouver, BC (on the PIA VPN)— both in Canada.

Working fine for me here near Denver.

Back in Australia now
