Apache Tomcat is back yet again

[DontCallMeShitley]

Pages were taking ages to load last night and just begun again. This time I got the dreaded Apache Tomcat again. Isn't it time this was fixed?
Tomcats should always be fixed if they are going to be let out in public.

Hi OP, sorry to hear that you're having trouble with this - how annoying. Would you mind telling us how you're accessing Mumsnet please so that we can flag it up to our Tech team.

We just need to know

• desktop site or app?
• which browser?
• which device?

Once we have that information, we can try to get some answers for you.

Thanks.

Seems to have stopped for now...

Maybe it is due to traffic?

Just got it when I clicked 'post message' on a thread.

Chromebook.

Me too when I clicked threads I’m on. Safari on iPhone iOS 12.4.1

And again:
