Amazon cloud-computing unit facilities in the Middle East were experiencing power and connectivity problems on Monday, after the company said its UAE data center was attacked by “objects”, causing a fire.

The UAE and Bahrain regions of Amazon Web Services were affected by the outage, it said, citing local power issues for both regions.

The company said on its status page that two zones of the Amazon cloud unit in the UAE, which are clusters of data centres, were without power on Monday.

AWS said on Sunday that an area data center in the UAE was affected after “objects” struck it and caused sparks and fires, prompting a power shutdown.

“We can confirm that a local power issue has impacted another Availability Zone in the UAE region,” AWS said.

AWS did not confirm or deny when asked earlier whether the UAE incident was linked to Iranian attacks on neighboring Gulf states, including the UAE and Bahrain, in response to US and Israeli attacks on the Islamic Republic.

The cloud firm earlier on Monday reported some improvement in the UAE region, but is now asking customers in other regions to rely on its services, saying it is working to restore power and connectivity.

The cloud division expected full recovery to be “several hours away” for both the UAE and Bahrain.

Separately, Abu Dhabi Commercial Bank (ADCB.AD)Opens a new tab said on Monday that technical problems were affecting some of its platform and mobile app users. It was not clear whether the lender’s outage was related to AWS.
