happy wednesday, friends of eggbug! it’s been a busy week here gearing up for a large infrastructure change that’s been months in the making. it’s the big one: we’re moving off of cloudflare as our CDN provider.
migration plans
we’ve been testing a secret second version of cohost running through our new CDN provider, fastly, and we’re satisfied that we’ve got things wired up correctly and have all our weird custom cache rules fully moved over.
we will be making the switch tomorrow, Thursday March 16 at approximately 10am PDT / 1pm EDT / @750. “The Switch” consists of us updating our DNS settings to point at fastly instead of cloudflare.
Potential Risks
- Things should be seamless, but your browser may experience strange behavior while DNS propagates. This is something we, unfortunately, have no control over. If you’re experiencing issues you suspect are caused by this, be patient! Restarting your computer and router should clear out your local DNS cache, but things can still be cached by your internet provider. These issues should fix themselves with time.
- There may be some performance issues if we didn’t get the caching rules right. We’re keeping a close eye on all metrics and will be fixing things as they pop up.
- Part of migrating off cloudflare means migrating to a different Web Application Firewall (WAF, one of the security layers in front of our severs) provider. In testing, our new WAF has not been flagging any false positives, but we will keep a close eye on it. If you are seeing your traffic blocked, please contact us immediately by e-mailing support@cohost.org (use the subject line “WAF Issues” and provide as much information as possible) and we will look into it.
that should be it! we’ll post before the migration starts, as well as and update once it’s done.
there aren’t really any other patch notes this week; the whole team has been fighting assorted health issues and all our “released” work was infrastructure-only. in addition to prep for the fastly migration, we also moved our scaling metrics internally to avoid issues like we had last week when our metrics provider was down for a full day. we’re currently using these secondary metrics as a backup, but will likely move to them as the primary source in the future.
we’re hoping next week’s patch notes will be a bit more exciting; we’ve got a Secret new feature coming up that we’re all extremely stoked about. there’s some more work that needs to be done to fully land it, but we’re hoping it’ll be live soon.
that’s all for this week! thanks, as always, for using cohost!
