@Hedonprincess you might have already seen the technical details, but I'll link them in case: https://assemblyfour.com/switter/cloudflare-fosta-sesta

In short: caching and performance for switter.at was provided via Cloudflare (based in the US). They proved untrustworthy, and now it's provided by CDN77 (based in the UK).

I think it'll be a rocky few months (hopefully that short ...). Also, Assembly Four is doing an amazing job.
