Skritter has been getting stuck quite often for the last hour or so.

It was going OK around 2 AM GMT, but since 3 AM GMT it gets stuck, see picture.

I'm in Taipei. I tried skritter.cn but it seems even slower.

Same for me in Shanghai since a couple of hours, I'm very unhappy, as I had reserved the Sunday morning to get all my reviews done and get the backlog close to zero - now I've given up.

same here in Australia. its just freezing every two characters for minutes at a time. thought there might have been somethign wrong with my internet... guess not. giving up right about now too.

This started yesterday afternoon for me in Japan. Today it is however much worse. I have an average of 40 seconds per save. I thought that where my fault since i added 500 Chinese pod lists but now it seems that you have this too. Same problem with both .com and .cn I switch to Anki for a few hours to see if this resolves. By the way, will it impact the speed to have a lot of lists? Chinese pod lists are very small and most of the words are the same so there is maybe only 1 or 2 words added per lists. I can't remove the list once I have studied it without removing the words. Maybe export all my words to one list and nuke my account to get it down to one single list?

Can't see any problem on app engine side: http://code.google.com/status/appengine/detail/datastore/2011/06/18#ae-trust-detail-datastore-put-latency

There seems to be no alerts on any of the meters.

Also for me. Hangzhou. So SLOW

Yeah I thought last night it seemed a little slow and now this morning it's basically unusable.

same for me in beijing, not really working atm

Our App Engine response times are off the chart for the past few hours. I'm not sure what's going on with it, but I'm looking into it and trying a few workarounds.

I've added a day to all y'all's accounts. Sorry about this downtime!

I think we need to expedite our plans to switch to App Engine's more reliable datastore pronto. This shouldn't happen at all after we do that, but we're behind on transferring the data to make the switchover.

I got Roland's reply by email... 1000 times and counting over the last hour... That can't be good!

Last 2 days, extremely slow for me in Taichung, Taiwan :(
So, at least I can see I am not alone

For me, it's also very, very, very slow. :(

Yeah, same here. I am using http://www.skritter.cn from Kunming. Yesterday morning, afternoon and evening seemed fine.

Hmm... Wouldn't you know it? As soon as I chimed in it seems to start working just fine... Used it for the past 10 minutes or so, no problems.

yeah, i had skrittered for some 40 min's now, also fine

yup it's working better now

the flood of forum emails (all the same) also stopped, at 15:12 China time. I got nearly 4000!

here also working smooth now, wow 4000 skritter spam mails!!;-)

Does the speed green/yellow/red indicator at the bottom of the study page always refer to server responses or does the local internet connection play a role as well?
Today the flash app's responses are unusually sluggish, and I wonder if it's my slow web connection. Server response times are regularly at 1000-2000 ms.

(I also considered the remote possibility that, at least for users with many items, excessive over-studying increases latency as data queries need to work through larger parts of the database.)

It's from the server to you, so yes your local internet connection matters.

Eg. If I'm studying on a train it's permanently red...
