When submarine cables fail, can www.ctbcbank.com still load normally?

Based on the latest test, under a submarine-cable outage scenario www.ctbcbank.com “may work.” If international connectivity is cut or blocked, the site may still remain available.

Why might www.ctbcbank.com “may work” when submarine cables fail?

During testing, resources used by the homepage of www.ctbcbank.com appeared obtainable within the country, and we did not find clear international-cloud dependencies. That means when cables are cut or connectivity is blocked, the site has a relatively better chance of staying up.

Does this mean www.ctbcbank.com will definitely be fine during severe cable congestion?

No. “May work” only means the homepage test did not show obvious high-risk dependencies. It does not guarantee that every page, login flow, API, database, or other function would behave normally.

How is resilience for www.ctbcbank.com under cable outages assessed?

When opening the homepage of www.ctbcbank.com, we observed 4 requests across 1 domains.
If any involve connections abroad, the outcome is classified as “Will not work.” If there are no foreign connections but there is reliance on in-country nodes of multinational cloud services, the outcome is “Uncertain.” If connections are only domestic aside from that international-cloud pattern, the outcome is “May work.”
