Result table metrics not loading — www.opents.xyz API unreachable

[Zaltarba]

The result tables on /OpenTS/result/#multivariate_forecasting (and the univariate forecasting tab) aren't showing any metrics anymore — the filters and page UI load fine, but the actual grid stays empty.

Dug into it a bit: result/forecasting/multivariate/table.js and result/forecasting/univariate/table.js don't have the data baked in — they fetch it live via POST requests to https://www.opents.xyz/forecasting/multi/query and .../uni/query. So the tables are entirely dependent on that external API being reachable.

I tried hitting www.opents.xyz directly a few different ways (homepage, a random nonexistent path, the query endpoint itself) and got nothing back at all — no status code, no TLS handshake, just silence. That points to the domain being down or DNS not resolving, rather than anything wrong with the frontend code.

Worth noting the failure is completely silent to users too — when the fetch fails it just falls through to an empty-table state, no error message. Might be worth a quick "couldn't load data" fallback regardless of the underlying fix.

Could someone check on the hosting/DNS for opents.xyz?

Thanks for the detailed investigation!

The issue was caused by the external data service being unavailable, as you pointed out. We have restored the original functionality, and the forecasting result tables should be loading metrics normally again.

Thanks again for reporting this and for digging into the root cause. The issue has been resolved, so this issue can be closed now.
