Https://blockexplorer.nu/ is down

[zoro]

We just need some mirror servers.
Is it open sourced? Can anyone (without special knowledge) set it up in another server?

It is open sourced.

CoinGame/NuExplorerOS

I did not manage to get it running… but I have 0 experience with nodejs and mongodb. That seems to be a problem.

For standard stuff https://explorer.coinpayments.net/transaction.php?chain=17 is sufficient.
It only tracks transactions and no motions or grants, but runs quite stable (I use it rarely, but have never recognized an outage).
https://svr1.nubitsexplorer.nu/chain/Nubits is available as well, but isn’t able to decode scripthashes to addresses (necessary for multisignature).

To show what I mean - this is the same tx ID:
https://svr1.nubitsexplorer.nu/ (can’t decode BqyRzFtWXDmjxrYpyJD42MLE5xc8FrB4js)
https://explorer.coinpayments.net/ (can decode BqyRzFtWXDmjxrYpyJD42MLE5xc8FrB4js)

Slightly off-topic: if this is valuable functionality I can ask Matthew to add this when we have further updates for NuDroid? My suggestion is to invest in the stability our main explorer as the first priority. Still hope someone can elaborate what Shareholders can do to improve stability.

Aaaaaand… down again:

Website is offline No cached version of this page is available.

@Ben, @JetJet13, can you please kick the blockexplorer?

[Cybnate]

Appears to work again. Thanks.

Blockexplorer down again. Can you please have a look? @JetJet13

Works for me again. Thanks for fixing.

Hey guys,
I just wanted to let you guys know the current reasons as to why the explorer is either

1. falling behind
2. not responding.

---

1. The explorer is falling behind because after some time of having the nu client running, it becomes unresponsive and so the parser script doesn’t run and the explorer falls behind. The current solution is to restart the nu client and wait for it to catch up so I can insert the missing blocks.

2. The explorer becomes unresponsive (as in you can’t load the site) because there is some function/api that runs and some parameter causes it to not return a value making the server wait ‘forever’ for a response and causes all other requests to hang. The current solution is to simply restart the node server.

@Ben, @JetJet13 http://blockexplorer.nu/ is down and doesn’t repond at all.

Seems down again. A gentle reboot would be appreciated.

I think we should really fund the improvement of the block explorer.

I think we should really fund the improvement of the block explorer.

I would seriously consider such a proposal. The Blockexplorer is a key tool in the ecosystem, but the blockexplorer downtime is unacceptable imo. I believe this can be fixed with more robust code (preferred) or just some clever monitoring of processes and when they fail just trigger an automatic restart of those. The latter is not elegant, but at least it decreases the downtime if we can’t afford to improve the code.

If someone can write a job description, I can try to find someone.

Coinerella would be interested, but projects like this are very time consuming and thus costly.

I would suggest a HTML/JS/CSS frontend with a PHP backend and Couchdb as Database.

Blockexplorer.nu is currently using Node.js.
I tried to install it on one of our servers, but I couldn’t do it.

Not a fan of rewriting it due to the cost. We just need someone to look after it in the first place. Just monitoring it and put some auto notifications in place to be alerted when it doesn’t work.

Only when the maintenance costs prove to be very high due to the chosen products to develop this, I would consider a rebuild.
