Bitbucket repository archive download sluggish last few days

Hello,

We use repository archive downloading functionality as part of our automation. After Bitbucket incident a week ago (https://status.bitbucket.org/incidents/z029156p1svh) this functionality is much less reliable.
Repositories downloads often times out (for downloads of few MBs to few dozen MBs - that normally take just few seconds); sometimes the downloaded zip archive is invalid.

Is there any new throttling mechanism limiting this feature?

We can provide exact times and links if it helps the investigation.

Thanks and regardds
