Most of Twilio is working. The status page shows must things in green. The same could be said of Twitter. However, in both cases, there have been serious issues. The difference is Twilio is paid to keep these features running, whereas with Twitter, less so. Even then, people were losing their job at Twitter just a few days ago because they couldn't explain why their CEO's tweets weren't popular. There have been numerous reports of Twitter failing at properly handling CSAM despite claims by their CEO. There were reports of massive issues with regards to getting service for advertisers. Robust? No. I mean, if the only thing you look at is your feed, maybe? But that's not Twitter.
