This is what happens when MD decides for new comment system that adds more complexity. Nothing is loading. Fix your shit already and remove the unneeded comment stuff.

How about now?

Same problem here, be it on a manga page or Follows/Updates

 

[TrainableMetal]

So I am not the only one seeing what's going on the website.

Got this error, refreshed after a min and it works again, but now it doesn't track my read/unread chapters.

 

[re_xavier]

Same here, refresh and clear cache do nothing. What's going on?

Edit: It's fixed for me now. How about you guys?

 

[cybeast21]

Same here, I thought it was my ISP problem

 

[Dverin_Oshiban_Duren]

Ok now it's back, right?

 

[monkey123]

For now working.

 

[TrainableMetal]

Works for me.

We're currently experiencing some performance issues.
The team is currently investigating.
More information will be shared soon.

And no, the new comment system has nothing to do with it

 

[hypo]

page loading is still intermittent, and chapters read status also fails on some loadings

I see, thanks for the info....... i still expereinced error interminently and sometimes the forum failed to load as well (backend something, something) anyway... i hope it got fixed soon

 

[monkey123]

errors again

 

[SiKucing]

They've had MT and it was fine for a while, until it broke again. I think mangadex should really do a proper MT even if it is a long one to really fiz the issue.

 

[monkey123]

All up again. So it looks like it's easier to access forum based chapter discussion if there are still 0 comments.

Now link

Create a thread in the forums

is available for plebs like me. No need to go to dev site with extra login. Okay okay, here is your deserved well done!

From Status Page:

Monitoring - A proper fix has been implemented and we will closely monitor the status of the site over the coming hours.

Short postmortem:

• Computing title ratings site-wide is very expensive (mainly because of the usage of bayesian rating in this case),
• So this computation is done ahead of time, once per hour, and its result is stored in memory for quick access in the meantime,
• However the space we allocate in memory for this (& similar things) has grown and grown over time, and just today passed the maximum allocated total size for it, causing automatic eviction of some values from memory (Redis maxmem + lru eviction),
• When this value is missing, the site attempts to initialize it, and when it tries to do so multiple times per second it causes extreme strain on our databases, and in turn an outage

In funny tldr layman terms:
We need to download more RAM to shove more maths in the memory or else the servers will overload and burst into flames.
