Explorer: Lacks outage information during downtime

[ngundotra]

Problem

When consensus is halted, the explorer website shows no information about

• why the outage occurs
• expected downtime length
• where to find more information as a user, developer, or validator
• what to expect as network comes back up (ie how long for on-chain clock to match off-chain unix time)

Proposed Solution

2 things

1) Show outage info on homepage of explorer: Open to discussion here. Minimum relevant info: i) Where to find more information (#mb-validators, official twitter account, perhaps even subscribe for email/text update) ii) Hypothesis for downtime iii) Postmortem for downtime iv) Would like to also have a link to docs.solana.com about:

• What is effect to on-chain programs (i.e. vesting schedules, staking, etc)

• Downtime history & what was done to fix each time (+ technical info for validators / indexers, like which hashes were used to restart from)

2) Add a megaphone: @steveluscher's suggestion is to add a red banner to explorer.solana.com with succinct info (ie a link to finding more information)

Some of the items you mentioned sound similar to information available here: https://status.solana.com/

Totally! That site is powered by Atlassian StatusPage; presumably they have an API that we could use to pipe the exact same megaphone messages to Explorer, if that's something we decide we want to do
