Yes! This has happened with me as well. The bug report can be found here

Hey everyone, we're experiencing some infrastructure difficulties. Specifically around loading repls. You might still be able to load your repl.

Earlier this morning we had a huge surge in traffic that caused a cascade of issues we're trying to debug. We're unsure if the traffic surge is legit or caused by a DDoS. Please bear with us.

Repl.it is down at the moment
