    *********** world productivity in IT instantly: @SlackHQ down @NotionHQ down What's next ? Might call it a day at this point ...

  • ffejnosliw Jeff Wilson (@ffejnosliw) reported

    @GuppyMFJ @SlackHQ I never organized them after the last outage so I guess I’ll have to consider that a win now.

  • MatthewZachary #WearAMask | Matthew Zachary (@MatthewZachary) reported

    Is @SlackHQ being down on the first day of the work week in 2021 an omen?

  • arturot Arturo (@arturot) reported

    Actually, @SlackHQ is not back and this is not funny anymore. Fix it, guys!

  • AmyPivo Amy Pivo (@AmyPivo) reported

    Every single time @SlackHQ is down I go through this fun routine. Me: what's wrong with slack? Part of brain I should listen to: probably another slack outage. Part of brain I actually listen to: you're getting fired and someone turned off your permissions early.

    @SlackHQ outage today killing productivity... #revengeof2020

  • HiImMateo Matthew Saunders (@HiImMateo) reported

    Fix your **** @SlackHQ

  • fwiffo Joey (@fwiffo) reported from Evansville, Indiana

    Sending best wishes to the @slackhq SRE teams. I wouldn’t wish a major outage on anyone, let alone first thing after a holiday break.

  • ashleyrjester Ashley Jester (@ashleyrjester) reported

    Feels right that the first day back in 2021 would start with a @SlackHQ outage

  • SteveRidzyowski StevenRidzyowski (@SteveRidzyowski) reported from Jamesburg, New Jersey

    @SlackHQ is down for us #slackisdown

  • CharlieGroll Charlie G (@CharlieGroll) reported

    @NotionStatus @NotionHQ @SlackHQ and (seemingly) random sites are also having outages. I'd tell you exactly which ones, but I can't really keep track since Notion is down 😭

  • solutionarchie The Solution Architect (@solutionarchie) reported

    Clearly too many people have gone back to work today to make @SlackHQ go down like this. Time to revert back to @MicrosoftTeams?

  • LenaLovesStuff Lena Anne Krug (@LenaLovesStuff) reported

    Hey, engineers over at @SlackHQ if we were still in offices I'd send over a bottle. I know how stressful an outage is! You've got this!

  • fshley AFM (@fshley) reported

    How am I supposed to shitpost with my coworkers if @SlackHQ is down

  • cheek0 Michael DiCicco (@cheek0) reported

    Who wants to wager that the @SlackHQ issues are related to auto-scaling down over the holidays and getting slammed as the east coast and then central started working again?

  • dejno Dejno (@dejno) reported

    Welp. @SlackHQ is down. 2021 — Let’s try again tomorrow.

  • gadevenyi Gabriel A. Devenyi (@gadevenyi) reported

    First day back to work, still remote: @SlackHQ down...

  • torresariass Santiago (@torresariass) reported

    Last year today we were about to enter WWIII, this year @SlackHQ is down. I'd say 2021 is not doing that bad in comparison...

  • shsteimer Sean Steimer (@shsteimer) reported

    I feel really bad for anyone who works in engineering or support @SlackHQ today. Coming back the Monday after a long holiday and dealing with a global outage has to really suck.

  • gwachob Gabe Wachob (@gwachob) reported

    Apparently 2021 is cancelled. @SlackHQ is down.

  • hafs__ hafs' (@hafs__) reported

    Forced all communication to @SlackHQ last year and now it’s down, and everyone is LOST.

  • CoderOsama Osama 💻 (@CoderOsama) reported

    Slack is down ????? @SlackHQ

  • JesseLeeRuiz Jesse Ruiz (@JesseLeeRuiz) reported

    @dev_jmitchell @SlackHQ Seriously! I wonder if everyone else at work was like, “Alright, let’s get going” SLACK IS DOWN “Hmm... is this a sign???” lol

  • little_2d Little (@little_2d) reported

    Of course @SlackHQ is having an outage on the first day back to work...

  • jdrosen2 Jonathan Rosenberg (@jdrosen2) reported

    My desktop @SlackHQ app is showing outage status, not allowing me to reconnect. No quit option either. Clever solution to help reduce the self-inflicted DoS attacks which otherwise normally occur as everyone tries constantly to reconnect.
