Some interesting stats.
Right now I have channels with 366 peers in the Lightning Network. Out of this number :
• 116 have a Twitter(X) account
• 105 have a Telegram account
• 78 have a Nostr account
...and...
• 193 (52%) doesn't have any contact information at all - at least I couldn't find it.
Please be sure to provide some contact information on the Amboss (https://amboss.space/) and/or LN+ (https://lightningnetwork.plus/) websites! It's not about chatting or something, it's about the ability to contact you in case of problems with the node or other emergency situations, which can save quite a few of your channels.
If you are concerned about privacy issues, use Nostr (https://nostr.com/clients) - that's really great decentralized and anonymous network.
Let me remind you that Sunny Sarah ☀️ node is present on the following social networks :
• Twitter (𝕏) : @ SunnySarahNode
• Telegram (DM) : @ SunnySarahNode
• Telegram (announces channel) : @ SunnySarahNodeAnn
• Nostr (pubkey) : npub1mggh5pryurepctujtlakafkj3n8x972e8dnshyv22fdycku3f8dsfd5d3r
Follow me and we'll be in touch : )
And encourage other noderunners to provide contact information, that's really important!

If your node starts to accumulate pending HTLC's rapidly, channels get disabled and eventually the node stops working, try stopping or restarting the Circuitbreaker if you are using it. Everything will be fixed instantly.
Already a dozen cases, including in low-load environment.

Sorry guys, there is some instability of my Node these days. Intermittent network issues. Will be back to normal operation ASAP. All expiring HTLCs are under constant control, I do not expect any channels to be FCed. Thank you for your patience. The fastest way to contact me for any questions is Telegram ( https://t.me/SunnySarahNode ) - feel free to message me if anything.

Actually, you can't open a channel with this node now. There is no address to connect.

A few tips to prevent FCs with online nodes due to HTLC expiration if you are LND.
1️⃣ Update your client to the version 0.16.2 ASAP if you haven't done it already!
2️⃣ You can restart LND a few blocks before HTLC expiration. Very often immediately after that the problem HTLC is resolved.
In order to speed up the restart, you can temporary disable DB compacting by modifying the following string in the [bolt] section of your lnd.conf file:
db.bolt.auto-compact=false
This is absolutely safe, but speeds up restarting process significantly (up to few minutes or even less). You can restart LND more often and without any harm.
Then, when the dust settles, this value should be returned back to "true".

It's MANDATORY to increase Time Lock Delta in channel policy for each of your channels. Min = 80, ok = 120.

Nevertheless even with this, I still have few more FCs, that happened when both nodes were ok and online, and my peer and I just sat together and looked at the expiring HTLC block-by-block, not being able to do anything.
Tried many things. Examining the logs. Will try to provide more details soon.
Some of node operators prefer to set fee walls to avoid any HTLCs these days (use rejecthtlc=true in lnd.conf if you are LND instead!).
We've lived through a lot, will survive this as well.

Absolutely devastating FCs nowadays. Several FCs can eat up all the income accumulated for long term. It seems that right now you are not getting paid for routing, you pay for it youself instead : )
Please, keep your node updated to the latest version, online and stable as much as possible. Although practice shows that this is not enough and the good channel can be FCed even if both nodes are online and ok.
Feeling upset...

I've set 0/0 fee for all my peers (except few big vampires) and my node drowned in traffic, which led to some halts. The node is stable again right now. I'm continuing my experiments, uncovering the breaking points, watching how node operates under extreme pressure, collecting relevant data : )
Sorry, guys, for instability of the node lately. I'm being very careful not to cause FC's from my side. Rebalancing is going to be less aggressive these days as well.

#[0] is a bit optimistic today ☺️

Just a small experiment with fees right now. Don't worry, everything will be back to normal soon. Sunny Sarah ☀️ always has as low fees as possible, most often even 0 💪
