Since yesterday, February 9 2015, 11 PM (CET) my VM experiences frequent periods of unresponsiveness. It seems to appear in waves, where for 10 minutes, web requests are timing out and RDP Connections fail. Then, for about 10 minutes, everything seems to work mostly normal, before the issue appears again.
When I'm able to connect over RDP, i see lots of this warnings in System Event Log:
Event ID: 153
Source: disk
The IO operation at logical block address 0x10e1e10 for Disk 0 was retried.
It seems there is something wrong with Storage ... but I see no alerts about current issues in the Azure Portal, so I'm wondering what is going on here. I tried to restart the VM, but it didn't help.
What could be going wrong here?
Edit: VM Location is WEST EUROPE.
Thanks
