[google-cloud-sql-discuss] Re: App Engine to Cloud SQL connectivity problem

There was an issue with Google Cloud SQL high latency that has been resolved for all affected users as of Thursday, 2017-11-30 02:46 US/Pacific.

We will conduct an internal investigation of this issue and make appropriate improvements to our systems to help prevent or minimize future recurrence.

For any kind of billing-related issues you should contact the free Billing and Payments Support.

It's still an issue for me, and today it's worse than before. About 4-5 days ago i saw no errors, but starting from today i see hundreds and hundreds of them. Stackdriver reports from time to time that my site is down for few minutes. There is also DeadlineExceededError while app tries to connect to Cloud SQL (seen in the logs). Moreover, as a side effect, because the website doesn't respond in the appropriate time, App Engine creates 19 additional instances and I've got billed to their CPU-hours. My appid is "armorinspector" if that helps.

Hello Andrew, engineering is aware of this issue and a fix should soon be rolled out to address it.

In the past couple of days I started to see hundreds errors in the log like this one:

"Lost connection to MySQL server at 'reading initial communication packet', system error: 38"

Previously it was maybe one or two such errors per day, but now they appear every few minutes. Nothing was changed on my side and I believe something is wrong with Google SQL. Errors in the log started to appear at 2017-11-08. I can't reproduce it myself and most of the requests are handled properly. I have about 180k requests per day and several hundreds of them are now failing due to this error. Anyone else experience this?
