"Hey guys, remember when _all of IRC_ went down?"<p>Obviously this sucks and I feel bad for all of those affected, especially the people fixing this or who depended on Slack for their workflow.<p>But it's hard to overstate the dangers of over-centralisation like this, and I say it as a person who uses Slack professionally.<p>Maybe running your own Zulip instance isn't as sexy or has the same integrations, but at least you can have a person responsible for fixing it and get status updates, and ultimately: as much as Ops is a dirty word; being able to plan your downtimes can help a _lot_.
