I think this was a interesting question.
From my perspective I have signed into HIv at all hours of the day and night, and hive website is always up.
I am active on many hive-engine websites and they are much more unstable, experiencing downtime.
I asked Gemini this question:
As of May 2026, the Hive blockchain—which powers decentralized blogging sites like hive.blog—has experienced 100% uptime, with no recorded incidents in April or early May 2026. This makes it extremely reliable.Conversely, Facebook operates as a centralized platform with 99.99%+ uptime but has experienced significant, long-lasting global outages in the past.Uptime Comparison: Hive vs. Facebook (2026 Context)Hive (Decentralized): Because Hive is a decentralized blockchain, it lacks a "single point of failure." It relies on a network of 20+ active "witnesses" (validators) producing blocks every 3 seconds. If one node goes down, others immediately take over, resulting in nearly continuous operation.Facebook (Centralized): Facebook operates hundreds of thousands of servers. While they use rolling updates to keep the site online, a central database or DNS failure can cause widespread, complete outages affecting billions of users.Summary of Differences:Reliability: Both are very reliable, but for different reasons. Hive is reliable due to decentralization, while Facebook is reliable due to massive infrastructure redundancy.Security: Hive's data is stored on a transparent public blockchain, whereas Facebook's data is housed in private, proprietary databases.Independence: Because Hive is decentralized, the site cannot be trivially shut down by a single entity. Facebook can be taken offline by its own technical errors or corporate decisions.Note: In 2022, there was a separate, centralized social app named "Hive Social" that experienced major, long-term downtime due to security issues. This is entirely separate from the Hive Blockchain (HIVE) mentioned above.
So it seems my instinctive response is correct: hive is up the majority of the time.
@steempty I have written a Proposal for DHF. I would appreciate it if you woud look at it and provide feedback: #374 Link
