Hi, one of the irccloud team. Can answer any questions if you like.

Some info:

* Erlang, haproxy, rabbitmq, redis, postgres, cassandra, chef

* 10+ billion irc lines stored at the last count

* Thousands of IPv6 IRC connections - we give each user their own IPv6 address. Main site also works over ipv6.

* Thousands of IPv4 connections too

* Open source android and ios apps: https://blog.irccloud.com/mobile-apps-open-sourced/

* API: https://github.com/irccloud/irccloud-tools/wiki/API-Overview

* Details on our security, password storage, etc: https://www.irccloud.com/privacy

I've mentioned this on HN before, but we moved our hosting off Hetzner and on to Black Lotus for the ddos-protection.

We see fairly frequent ddos attacks, from a few hundred mbit to 10+ gbit. They aren't impacting service since we moved to black lotus.

Can you share what you store in each of the databases?

Here's what I'd speculate:

- Redis: message lists for active users

- Postgres: account details

- Cassandra: all messages

Thanks.

Yep, postgres has all the account / user details, lists of what network and channels to join, billing etc.

All the irc messages end up in cassandra, via rabbitmq. We use local redis as a cache for the most recent messages. Our cassandra cluster is on EC2 (~11ms away from our other hardware, which is in LA).

Please can you wire up some unicorns to some rainbows and make it so I can have irssi act as a client for irccloud? ;)

I really want an IRC kernel with an API, so I can have all sorts of clients on different machines/platforms, but it seems to be impossible at the moment, without using the horrible bouncers.

Isn't this what Quassel http://www.quassel-irc.org/ does, or am I misunderstanding what you're asking?

What's wrong with bouncers? ZNC has been serving me well over 5 networks for years now. I don't see the appeal in an in-browser solution at all.

Isn't that what dircproxy does?

Thanks.

For me, it's only really useful with a backlog of perhaps 7 days, the rest I would like to have permanently deleted, it would make me feel more comfortable using the service.

Maybe not make this the default behaviour, but an option would be nice.

Out of curiosity, what causes you to be "comfortable" (or not) with a service keeping a record of your IRC activities? I assume you have private networks in some form?

I'm not judging, i simply ask because a lot of people are connecting to Freenode/Freenode-like locations where he majority of the channels are already logged 24/7 by you, countless others, and bots publishing the content to the web.

Great, work, I tried it, got my invite and logged into my Freenode channels. Very nice!

Is this the place to ask for colour input? IRCCloud displays colours fine, but I can't figure out how to use them in my own messages.
